Written Review

Apparently in Japan there’s a type of bicycle called the Mamachari or “mom bike” that’s easy to approach, with a low stand over height, and very useful, because of its front and rear rack provisions. These bicycles are frequently used to transport children and goods around town and they inspired Kiyoshi Iwai, a Japanese transplant to America who spent more than a decade in the steel industry, to create a modernized electric assist version. The CERO One is the culmination and evolution of that creative endeavor and Kiyoshi and his business partner Felipe are launching it now in 2017 after three years of work. The One is what I would describe as a compact cargo e-bike, it’s capable and sturdy but doesn’t require the garage or apartment space of full sized models like the Yuba Spicy Curry. Measuring 72″ long and just 15″ wide when the handlebar is turned, it will fit into elevators, slide into bike racks, and squeeze into closets (when tipped up onto the rear wheel). You can only get this electric bicycle in one frame size at the moment, but the stem is highly adjustable and they claim it fits riders from 5’1″ to 6’4″. The stem telescopes up 100 mm and 110 mm stem adjusts from 0° to 90° so you could effectively double the height or position it way out to extend reach. Both adjustment parts are made by Satori and I appreciate the two-bolt clamp that will keep this stem secure on long bumpy rides. Many cheaper adjustable angle stems only use one bolt and can rattle loose as you ride over cracks and go off curbs. For this video review, I took the CERO One across grass, reached the top assisted speed of 20 mph, and forced a motor stall on a small hill. The bike felt pretty good even though it’s built around a rigid frame. There’s no suspension fork, seat post shock, or large plush saddle. Instead, you get a swept-back gullwing style handlebar with premium ergonomic grips and an active Ergon saddle. The tires are wider than normal at 2.15″ diameter and have a 30 to 55 PSI rating so you can lower the pressure a bit to improve comfort at the cost of efficiency. This is a more active bike, one that requires you to pedal vs. relying on a throttle mechanism, but it gets incredible range (between 35 and 90 miles depending on the level of assist chosen). The unique 26″ rear wheel and 20″ front wheel layout keeps the front rack low and steady, out of your view, and improves strength. It turns corners tight, has a walk mode feature (hold the down arrow to activate and then hold again to make it go forward slowly).

Driving the bike is a geared mid-motor from Shimano, the same company that produces the hydraulic disc brakes and 10-speed drivetrain. Their STePs electric bike system is light, efficient, and still very capable offering 50 Newton meters of torque, but it’s not as strong as the Bosch CX which offers 75 Nm or the Brose which offers 90 Nm. By comparison, many high-powered hub motors offer 20 to 40 Nm. I mention all of this because we’re talking about a cargo bike here. And it doesn’t have a NuVinci CVT or internally geared hub that can be shifted at standstill. You have to plan your shifts in advance and leverage low gears to get the motor to climb effectively. If you stop on a hill without shifting down and have a loaded bike, the motor may stall when you start from zero again. This motor is relatively quiet but does produce an electronic whine as you pedal faster or use the highest two assist levels. It is bolted onto a custom bottom bracket mount and keeps weight very low and balanced on the frame. Same thing goes for the 5.8 lb battery pack, it’s low and mounted near the motor. I love how CERO considered chain movement when mounting the motor and double-leg kickstand, notice the little sprocket just below the chainring. This raises the chain so it won’t rub and it also keeps it tight as you ride over bumpy terrain. Unfortunately, it seems like they forgot to add a slap guard sticker on top of the chainstay (or just didn’t think this was an issue). Sometimes, especially on mountain bikes, the chain will bounce into and chip the paint on the right chain stay. This is something you can add yourself later. I do love the four color choices, especially the white because it will be the most visible at night, and would want to keep the bike looking as clean and new as possible given the $3,399 price point. Felipe explained that they really scrutinized the paint and chose a 50/50 blend of gloss and matte to reduce fingerprints. Some final thoughts on the motor, it turns a 38 tooth sprocket which is protected by a plastic guard on the outside, it would be nice to have a guide here to keep the chain from falling off towards the inside but I didn’t notice this being an issue during my test rides. The 10-speed drivetrain is perfect for this bike and even has a Shadow Plus clutch to increase tension and reduce chain bounce if you are on rough streets. Just push the little grey lever into the up position. Leaving it down will make shifting slightly easier. And back to those brakes, with 180 mm / 160 mm you get plenty of stopping power and the adjustable reach levers are great for riders with small hands or those days when you might have puffy gloves on.

Powering the One is Shimano’s new BT-E8010 downtube mounted battery. It is way better than their older pack and here’s why… you get more energy (36 volts by 14 amp hours), it’s nearly the same physical size, it still slides out vs. clicking down (so the downtube and top tube can be very close together and lower the stand over height of the bike), and it uses a single charger interface vs. requiring a dongle. The electric bike charger itself is also improved, offering 4 Amps of power flow vs. just 2 or 3 as with most other electric bikes. The charger is a little heavy and bulky, but I’m assuming it’s safe and durable because Shimano is a premium brand with many years of experience doing electric bikes and electronic shifting. You can easily toss the charger into one of the baskets or a trunk bag on the rear rack to fill the battery at work or a friend’s house. Notice how good the black accents like those custom plastic venders, the grips, saddle, tires, motor casing, and battery all look on this bike. The thing is well balanced visually and you will be able to keep it looking nice because the battery and display are removable. It’s useful for lifting the bike as well, you can reduce weight by taking off all of the rack systems, the battery and display, and both wheels (which feature quick release). This does present the challenge of locking however, make sure you lock both wheels for longer stops. The rear wheel is easy to secure with the included ABUS cafe lock, and I love that it uses the same key as the battery. Consider a u-lock and cable to secure the front wheel and the rest of the frame.

Activating the CERO One is quick and intuitive. Once the battery has been charged and properly mounted, just hold the power button on the left side of the display for a few seconds. This will allow it to boot up and show your current speed, assist level, trip stats, and battery percentage. Hooray for Shimano, going with battery percentage vs. a five or ten bar battery infographic. It’s a lot more precise this way and you can use the percentage in combination with the range estimator menus to plan rides. As you arrow up and down through the different levels of assist, the range readout will dynamically update based on battery level, recent ride activity, and that level of power being used. Shimano has enlarged their display to make it easy to read and the transflective LCD works well in low and high light conditions. The button pad is easy to reach and interact with when riding without taking your left hand off the grip, and there’s an annoying beep sound that chimes each time you do make a selection. Thankfully, by holding the up and down keys simultaneously, you can enter into the settings menu and turn off this beep, switch from metric to standard, even change the font color from black on white to white on black (much less distracting for night riding). Perhaps the only complaint I have about the Shimano STePs ebike system as of today is that it does not have a USB power port to tap into like Bosch and others. This is handy for charging a phone on the go, especially with the new enlarged 504 watt hour battery pack. You may arrive at your destination with plenty of juice to spare but no way to access it for your ailing phone. All automobiles have 12-volt DC adapters (those round things) to plug into, and many newer cars have USB… so when you pay $3.4k for an electric bike to replace your car, I feel that it should include some of these creature comforts. Note that the smaller Bosch Purion display does not have a functional USB charger, so the Shimano system is not alone in lacking this.

At the end of the day, I feel like the CERO One electric bike could either be a compact high-quality commuter platform, a capable cargo bike for a delivery person (food, boxes, etc.), or a parent’s bike for him or her. The design and colors make it appealing to men or women, in my opinion, and it would definitely take the effort out of having to pull a trailer, add 40 lbs of child seat + child, or a big load of groceries. This is a capable, high quality platform that I would expect to last well. Even if CERO went out of business someday, Shimano isn’t going anywhere and will support this battery type for years to come. I definitely appreciate the drive system improvements over prior year and have been excited to see a bunch of compact cargo capable models lately such as the Orbea Katu-E 10 and Riese & Müller Tinker. Perhaps something like the BESV PSA1 would be more comfortable because it has suspension, and it is lighter, but it’s just not going to be as powerful or efficient. The One has filled a niche and I’m excited to see how it does in the coming years, kudos to the team. Big thanks to CERO for partnering with me on this review and meeting me in Santa Clara to film. I always enjoy meeting the team behind the product and really digging in… and I absolutely love the bottle provisions on the front rack and bosses :D

Pros:

  • I was really impressed that they added a pulley wheel to keep the chain clear of the double-leg kickstand, this way the chain won’t rub when the stand is deployed! I was then immediately disappointed that the top of the chainstay does not have a clear plastic slap guard because it could get chipped up over time if you ride on bumpy terrain in high gears frequently, consider adding your own for ~$12
  • I love that this e-bike comes in four colors, the white appeals to me because it would be the most visible from the side when riding at night but all models have reflective paint accents and the black blends the battery, motor, fenders, and baskets the best
  • Most cargo bikes are long and wide, I love how the CERO One is only 72 inches long (that’s about the size of a regular bike) and has an adjustable stem that lets you turn the bar sideways to make it narrower
  • Whether you use this electric bike for cargo hauling or not, it’s very sturdy and nimble, the racks can be removed so maybe you only leave the rear on with a Yepp! child seat to reduce weight and keep it narrower? Many possibilities
  • Aside from the compact size and sturdy racks, one thing that really differentiates this bike is how easy it is to mount and stand over because of the mid-step frame and smaller front wheel, it feels stiff and strong but isn’t so overwhelming or difficult to mount
  • In the video review I kept commenting on the weight of ~56 lbs but I actually think this is great with both racks on the bike, fenders, lights, and larger tires… you can run the tires tubeless to reduce weight
  • The battery charges quickly thanks to a 4 Amp charger, it’s removable to reduce weight or charge separately for convenience (like if you commute) and the charger only has one plug now! No more dongle adapter which was easy to lose on older Shimano battery designs
  • I like have a range of gear choices (especially with a potentially loaded bike) and you get a quality 10-speed Shimano drivetrain here with Shadow Plus (the little grey lever) so you can position it up to tighten the chain if you ride fast on bumpy streets or down to loosen it for easier shifting
  • The Shimano hydraulic disc brakes perform very well, in some ways, the 180 mm front rotor is overkill because you also get a mechanical advantage from the smaller 20″ wheel diameter, these brakes are easy to use and have adjustable levers which is great for people with smaller hands
  • The rear rack has been tested to meet ISO heavier load standards of up to 75 lbs. However, CERO’s recommendation for the safest possible riding and handling of the bike is a combination of 55 lbs rear and 22 lbs front, or 22 lbs rear combined with 55 lbs in the front. They look good and have many mounting points but may require larger pannier clips because the side tubing is thicker
  • I came into this review thinking the bike did not have bottle cage mounts and then Felipe showed me that it does! There are two sets of bosses (one on either side of the front rack) and they include 10 mm spacers and mounting screws apparently, this positions your fluids or accessories within reach while riding and means you don’t have to leave them in the basket where they could roll around as you maneuver the bike
  • Very nice touch points, the Ergon saddle and Ergon locking grips are durable and active but tend to reduce hand and bottom fatigue which is key on a bike with no suspension
  • Unique pedal choice, the nylon platforms with imbedded grip here provide surface area and traction without the dangers of sharp pins that could scrape your leg if you foot comes off, it’s a good compromise and works well on this sort of bike even if your shoes get wet
  • The Shimano display really helps you overcome range anxiety because it shows a battery capacity percentage as apposed to some five-bar infographic and there’s a dynamic range calculation for each level of assist
  • CERO has been in the works for several years so even though they are doing a Kickstarter campaign and this is their first official release, they are more established than some other startup ebike companies and you get an excellent two year comprehensive warranty on the bike, the company is based in Los Angeles, California

Cons:

  • The headlight is mounted well, beneath the front rack, so it won’t get blocked… but it doesn’t point where you steer because the rack is frame mounted for improved strength
  • There’s no suspension on this bike so, depending on where you ride, you might want to reduce the air pressure in the tires to improve comfort a bit (the range is 30 to 55 PSI), consider a 30.9 mm seat post suspension but note that it will raise the minimum saddle height by about three inches
  • The new battery pack is relatively lightweight at ~5.8 lbs considering how much electricity it can hold (504 watt hours) but it isn’t as easy to carry as the older one, there isn’t a clear lip to grip at the top like there used to be and there’s no loop like the similar looking Bosch battery has
  • I love that the new Shimano STePs ebike charger is fast, putting out 4 Amps vs. just 2 or 3, but it’s pretty large and a bit heavy at 2.2 lbs vs. Bosch’s 4 Amp charger which weighs ~1.7 lbs
  • The chainring has a plastic protector to help pants and skirts slough over and stay clean but it does not have a full chain cover or a chain guide to reduce drops, just a minor question or consideration compared to some other models I have seen
  • The Shimano STePs mid-motor used here does not offer shift detection and you cannot shift at standstill since the drivetrain uses a traditional cassette and derailleur, I mention this because it could be easier to mash gears if you’re starting out with a heavy load and shifting while pedaling, try to ease off on pedal torque just before you shift to keep the chain, sprockets, and derailleur in good shape
  • The shifter cables, electrical wires, and brake lines are well hidden below the downtube, but they are not internally routed the way that some other e-bikes are, this clutters the visual appearance and exposes them to more dirt and water but also makes servicing the bike easier
  • Minor gripe or area for future consideration, I wish there was a USB port to tap into the battery and keep your phone, music player, or additional electronic accessories filled (the Bosch Intuvia display offers this)

I really don’t understand why bike / motor manufacturers are not just putting 750W (ie max power motors) on every bike. The cost of the more capable motors is fairly small. My guess is that as battery capacity in increased with the new 21700 cells and or Li Polymer technology the bike companies will stop putting 250-500W motors on eBikes. In reality the federal regulation of 750W max has virtually no legal standing because both controller and battery voltage are part of the performance equation and it’s not like the police are going to have portable dynamometers to test if a bike is compliant or not.

Yeah, apparently in parts of Europe the police do have portable tools that can test in the wild. I have only heard this from one person but they work in the industry so I sort of believe them. I think in the US we are just getting what they sell overseas (in large quantities) but spiffed up a little to sound powerful or fast. In reality, I believe that a lot of the mid-drive motors are the exact same hardware, just overclocked a bit. Lower wattage means lower energy consumption and lighter weight (as is the case with the Shimano system especially) and I’m fine with that given my lighter body weight, range has never been an issue for me though and I’m a more active pedaler.

Hello Courtney; I really enjoy your videos. I notice that in several of your videos you mention the lack of water bottle bosses on many of the E bikes you review. Like you I enjoy having a bottle accessible. I recently discovered a product that many of your viewers may enjoy. Revelate designs, a US based company, manufactures a product called the “feed bag“. It mounts onto the stem of almost any bike and allows easy access to your bottle plus storage for small items. Eg. cell phone, wallet. It can also be easily transferred bike to bike. Check them out.

Thanks for the tip Pekka, it reminds me of chalk bags for rock climbers! I have seen massage therapists who use similar contraptions to carry around massage oil and stuff. This is a cool accessory and a great tip, thanks :)

Court,

Thanks for another fine review. My question isn’t specific to the Cero bike, but since it uses the Shimano STePs drivetrain, I’ll ask it here. The top assisted speed for this bike is stated as 20 mph in this review. However, the Shimano website states “All three support modes will assist until 16mph.” Can you provide any information about this apparent discrepancy?

Reply

Hmm… you’re making me question my own experiences here but perhaps this is a geography thing. Like in parts of Europe they have a law that limits Class 1 electric bikes to 25 km/hr (which roughly translates to 15.5 mph). Maybe the resource you’re referencing is meant for that geography? I went to double check the website and indeed, saw the 16 mph reference here. Check out the Walleräng review video around 21:23 and watch for a minute. I film myself riding with one hand in the highest level of assist easily reaching 20 mph. So, unless Shimano has decided to tune-down their motors now or something, I think it’s a typo from their European spec.

I bought an 15 AH 48 v battery which I built a custom mount for on the front fork. It was 61 v when I started, at 60 miles where the controller/motor failed, it was 48 v. So that much AH should get you up the hill. With 40-50 lb load sometimes, I don't see putting the battery on the back or the middle. With 40 lb supplies + 25 lb basket + 160 lb me, my back tire hits the rim above 4 mph on bumps at 55 psi anyway - 1.9"x26".
Battery was from sun-ebike.com on ebay. Connectors are Dorman .157" bullet crimp, male+female for polairty. Good for 30 amps. Battery up front makes the bike look like a rhinoceros, but the uglier the less likely I'll find the chain cut & bike gone after shopping or a concert. All the screws and elastic stop nuts on the mount are an inhibitor to theft, too, compared to a bottle mount or hanger bag battery. Take 6 screws to get it off, and only I know which ones of the 20.

There are three bikes I really, really like these days. Two are electric:

Riese & Muller Charger GX https://www.r-m.de/en-us/e-bike/charger-gx/
Tern GSD https://www.ternbicycles.com/us/bikes/471/gsd
Co-Motion Siskiyou https://co-motion.com/bikes/siskiyou

Chances are when I upgrade from my great first e-bike it will be to the Charger (or whatever model fills that niche). I am intrigued by the Tern (and the related Cero One http://cero.bike) because it is an outside-the-box approach to what a bike is supposed to be, although they have both obviously borrowed from the Japanese mama bikes, Dutch city bikes, and folding bikes. Honestly, if the Tern came with a Rohloff hub I'd probably go for it over the Charger. Five years down the road it wouldn't surprise me if I had both a Tern GSD and a Charger in the garage.

The Sikiyou is a bike for a different kind of problem (although there is some overlap with the Charger GX). I've several friends who are hardcore bike tourers with an arsenal of different bikes. They have several Co-Motion bikes between them and I always found them to be awesome, honestly far better in the design and ergonomics of their bikes than any e-bike I have encountered. One of them got a Siskiyou this summer and is planning on using it to ride the Silk Road (yes, *that* Silk Road) next year. I tried it out for an afternoon last summer and was instantly in love. Or whatever emotion you feel when you really, really like a bike. If I were going to ride the Alaska Highway or a similar trip that would be the bike to have.

@indianajo SO many good suggestions, especially about wheel size, knobby tires, disk brakes. Regarding 15% grades, I think I have a few of those. Thank you for your thoughtful post.

More power to you. Great set of athletic goals for your future.
I'm age 67, going on 107 I hope. I also have no cartilage in my knees, plus bone spurs, related to Army service in the seventies. The more I ride the bike the less the knees hurt. I ride a bike everywhere I don't rent a U-haul truck, and the constant use has since I quit working age 58 dropped 55 lb , pulled rest pulse down from 85 to 64, cloresterol down from 213 to 130.
A few tips. You live in the US. I wouldn't want a small wheel bike like the tern or Cero above. We get potholes and uneven pavement in the US, up to 6" deep and separators up to 3" high don't get repaired for months. You want at least 26" wheels, to cut shock when you hit an elevation change. I missed it and hit a 2" pavement ledge last Saturday at 8 mph on Louisville river bike path , and had to push the bike up steps when park dept. allowed vendors to set up tables on the ramped bike path. For comfort I prefer 1.75 " (45 mm) to 2.1" (55 mm) tires or bigger pressured only to 50 psi. That pressure keeps me from denting the wheel on a sidewalk ledge I go over weekly with groceries. I use Kenda Full knobby tires which are a bit noisy, but grip better if I slide over the pavement edge, and have 500 % fewer flats than the thin street tires I was riding previously. I don't ride a suspension bike. I do have seat springs. Many pro level bikes won't take tires that wide.
If you go over 15 mph in the wet down hill you'll probably want disk brakes instead of rim, which are less likely to fade due to being wet. You'll want an aluminum frame if you ever intend to put the bike on a bus rack. A short frame big wheel electric bike reviewed here is the izip p3 protour https://electricbikereview.com/izip/e3-protour/
which has aluminum frame, disk brakes, turn back handlebar, a book rack, and comes in 3 sizes.
I ride 12 months a year, only falling back to riding the city bus to the grocery store when the city has pushed mounds of icy snow into piles in the bike lane & sidewalks. Black glare ice I won't ride on, but I will ride on snow up to 12" deep. I wear clothes to handle the temperatures. Extreme contractor grade gloves are required some times, available only at the farm supply or home store. I wear up to 5 layers some time, say 5 degrees F & below.
I need 21 speeds to get up 15% grades here in Clark Cty, including a 30:29 low low sprocket. Using that gear is slower than walking, but riding unloads my wrists & back twister muscles from pushing the bike. That is without electric assist. That means a triple front sprocket: 30, 42, and 52 sprockets, 29 to 14 on the rear. Bosch mid drive systems replace the front sprocket set with their own single, so IMHO they are not for pedal assist up steep hills.
See my current rides below. I carry up to 50 lb of groceries. Because of the uneven weight distribution this causes (85 lb rear 25 lb front without me or groceries) I'm looking at buying stretch rear cargo bikes like the yubabikes bodaboda http://yubabikes.com/cargobikestore/boda-boda-v3-24-speed or the kona ute https://louisville.craigslist.org/bid/d/kona-ute-large-like-new/6269725406.html
xtracycle also has a long frame cargo bike.
You'd want the taller step-over bodaboda of course with your long legs. Or the large kona. As you can see from my pictures, my leg inseams are short, 28", my torso is long, so I'm riding upgraded kid bikes.
Best of luck shopping and achieving your fitness goals.

I recalled this bike from one of courts reviews recently.

https://electricbikereview.com/cero/one/

Seems like it might be a very good fit. The new Shimano drive is supposed to have plenty of torque for your hilly area, and there 500wh battery at your size would give you fifty miles of range easily.

It sounds like regular maintenance won't be an issue with all the bikers in your family either.

The baskets would be s great fit for grocery shopping as well. I think they had some very interesting color options to boot.

You're correct - Cicero is about my halfway point. Unfortunately the CTA only allows bikes in non-rush hour periods. The other problem is my wife is terrified of me getting killed in traffic. I may have to wait until every road in the city has a barricaded bike lane, so maybe when I'm 65...

Dunbar

Cicero isn't 24 miles from the loop but so I assume you live further out. If the CTA allows bikes on the train another option would be to bike half of it and the the el the rest of the way in. The CTA prices are pretty reasonable IIRC. 24 miles is a long commute even for an e-bike. Especially if it's on surface streets and not some sort of dedicated bike path or MUP. I would want a class 3 bike that can do 28mph for that commute and that's going to require close to 800wh of battery life each way at those speeds (plus a recharge for the return trip.) I don't think that's possible at your budget.

I also realized I can go month-to-month on the transit benefit, so full-out snow adventures in December-February probably wouldn't be necessary. I am thinking of trying out the ride on my pedal-powered bike soon to see how safe I feel on the roads. Taking Ogden Ave in from Cicero was recommended to me by a friend at work who bikes a lot all over Chicago and its suburbs.

Your road pump is for emergencies, not maintenance. On the road you just want to get the tire inflated to the point you can ride safely. With experience you will get very close to the PSI range. Always have a floor pump at home, much easier to use. Don't go cheap on your floor pump, cheap pump's gauges are notoriously inaccurate.

Co2 inflators are nice, I have one in my commuter bag, but the RaceRocket lives on the bike so I'm never without it. You never need cartridges for a pump.

If you need something with a gauge you could go with something like this: http://www.topeak.com/products/Pumps/TurboMorphG You'll need more space for it though. Here's a pump/inflator: http://www.topeak.com/products/Pumps/hybridrocket_hp No gauge though.

Good luck!

I have a 2010 Kalkhoff pro connect sport, which I have used a great deal. The battery has lasted a lot longer than I had expected but is now starting to fail. The bike has a 250w Panasonic center drive motor that runs at ~26 volts. Replacement batteries used to be readily available but I am not having much luck finding one quickly. Also, I know that the batteries were upgraded in terms of capacity but I don't really need that capacity for my daily commute. Given the age of the bike I am a reluctant to spend the roughly $800 that the high-capacity batteries were selling for in the past. I'd appreciate suggestions about where I could get a suitable battery or whether the current battery could be re-celled.

As I am a big fan of users / Owners groups on Facebook I have made one for my new E-Glide S/T

In the past Owners groups like Rad ams Pedego have really helped me not only learn about the specific brand but also E Bikes in general.
So I invite anyone interested in learning more about E-Glides but E Bikes in general.
This new group will also be a place to review ans suggest accessories and additions to your bike.

You're correct. The salesman told me wrong. Regretfully, this is my second experience with a different LBS not knowing their ebikes. Frustrating. And I'm going to let them do the warranty work?

@ayVee@Chris Hammond I agree with your comments. In all honestly no one at this point really know for example what the true lifecycle is on a Bosch / Yamaha / Brose mid drive is going to be on average.

There a lot of riders in the world with 20,000 km's plus on their mid drives and they are still running smooth. I have a gut feeling that 30,000 Km's is not going to be an unrealistic #. But at this point I don't think there is anywhere near enough data out there. The good news is that they do last a really long time which is awesome.

With that much mileage most bikes (other than the high end ones) will reach a point of whether the remaning components (headsets, hubs, rims, tires, brakes etc.....) are also in good shape or whether it just makes financial sense to replace.

I am also looking at Giant and will test one soon. Also had a long talk with a local lbs about them. Great guy.
Was also struck by how narrow and thin the lbs inventory was. Of the hundreds of bikes, they had.2 ebikes in stock, both Giant. When I asked why he didn't have more... and my interest in say "Magnum", he said Giant restricted who he could bring in. Also sited that ebikes are still not hot here (CT), and the high cost of them...

My point is, it's a pain to have to shop around so much. No central aspect to this search what so ever!

Still real curious to see the Magnum Navigator discussed earlier.

@cooteretti I did learn the Bosch motors are preferred but yeah, this is going to be one of many hobbies so the budget is no more than 2 grand. That appears to be the Yamaha which I was told offers a lot of torque and folks here say are capable hill climbers. Just wish I could ride one up a REAL hill to know for sure.

Hi Jim,

I’m surprised that your new Expert Levo came with a SRAM chain. The Specialized website says the 2018 Expert should have a KMC X11ET (recommended above by LimboJim). X11ET chains came stock on our ‘18 Comp Levos, and they have held up well to lots of abuse riding in desert sand. However, we haven’t used them in the type of mud shown in your original picture.

In any case I wouldn’t give up on a bike due to something as simple as a chain. Try a different one, and monitor wear as LimboJim suggests. I haven’t heard of SRAM Power Links (or KMC Missing Links) being especially susceptible to failure when caked with mud, but perhaps you should just switch to a pinned chain. I’ve had good luck with Shimano XTR pinned chains over the years, but now I’m even using their new removable link on one of my other bikes.

Good luck.

Just so no one gets confused. The bike has a 400 watt hour battery, powering a 250 watt nominal, 500 watt peak Yamaha mid drive motor.

Scooteretti, you make a good point about flat repair. On a rear hub motor, rear wheel removal is far from quick and easy. That said, there are 2 easily viable workarounds to eliminate the need to even remove the rear tire in order to do a flat repair.
1) Take the tire off one side of the wheel with tire levers; remove the tube from tire (yes it is still pinned inside the rear triangle); find the hole in tube and patch it; check the tire for penetrating object and remove it; reassemble; inflate and go.
If the tube is irreparably damaged,
2) Carry a GAADI replacement tube, follow above steps to remove old tube, cut it in half and discard; place the snake shaped GAADI tube in tire; reassemble tire; inflate and go. https://gaadi.de/?lang=en
As you mentioned, there are pros and cons to any ebike. No matter what you choose, you are making a trade-off somewhere. We all have to find the bike that best suits our intended use.

Great reviews on E-bikes, I enjoy them.  When are you going to do the most badass E-bike on the market that doesn't cost as much as a Harley Davidson?  I mean, the Lithium Cycles Super 73.  They are so much fun!  They also have some newer, less expensive models available for pre-order now.  If you find yourself in Oregon you can do the review with my Super 73 Original, 2016.

Is that small tube between the upper and lower frames (just behind the battery) to now be on the production bike? The bikes on their Kickstarter and Facebook pages do not have that connecting tube. It might be structurally important and give the bike more stiffness?

Hello Lynn, great observation! Yes, for the final production version we added a connecting tube between the top and down tube for increased overall stiffness!

I bet you could put a tank of nitro on the back for some extra speed. You could hit 100 mph in a few seconds. Or if you don't like nitro you could put a basket on the rack to carry stuff. Nice bike.

You are right, unless using for some light transportation. But for cargo bike, Bafang heavier motor will give you the power you desire and help in the long run. This seems to be a weaker motor and give up easily on a slight strain.
