Written Review

The 2017 IZIP E3 Sumo is a complete upgrade from prior year models. Instead of using the mid-tier TranzX motor system, IZIP has opted for the top-tier Bosch Performance Line CX motor system. This thing offers 75 Newton meters of peak torque output, shift-sensing and shift recommendation, as well as a compact design. Electric bike shops that I visit regularly praise Bosch motors as being the most reliable… but they do produce a bit more noise than Brose due to higher RPM operation. The chainring is much smaller than you’d normally see and is rotated at roughly 2.5x your pedal cadence making it very responsive. In short, the motor generates a lot of power but whines a bit at high speed and can be vulnerable to chain suck if coated with mud. On some other Bosch powered ebikes that have rear suspension, pulley wheels and chain guides have been added to reduce chain slap, slip and kickback. The E3 Sumo does not have any of this additional hardware because it has a solid rear end but the chain suck thing could still be an issue. Notice how close the yolk and right chainstay are to the chain when riding in high gears… I saw the chain possibly bouncing into the joint where the yolk meets the stay in the video I shot and this gave me pause. Given the smaller chainring, narrow-wide teeth (that grip the chain) and tight chainring guard, would chain suck be an issue? I’m only theorizing here but it is an issue that has been brought up in the EBR forums before and fat bikes are designed for snow, sand and muddy riding. Depending on the type of terrain you intend to explore, I’d approach with these considerations in mind and possibly bring a cleaning tool. In the future, if this does present itself as an issue, maybe a lower guide will be added to the bike?

The frame on this thing is purpose built with internal cable routing and a custom battery motor interface. In order to fit a standard Bosch motor and align the chain properly, the motor has been seated to the right edge of the bottom bracket mount and a spacer has been added to the left crank arm. It has an alloy skid plate below but is otherwise much more compact than Bosh systems from a year or two ago which had bulky plastic covers and were mounted flat vs. at an angle. It’s an impressive design to be sure and the paint job looks great with digital camo stickers on the frame and battery and accents on the saddle. With two sizes to choose from, this bike becomes much more accessible and gives you the option of riding a bit small to bring in reach and make handling quicker. I love how steep the top tube is because this makes mounting and stabilizing the bike easier which is a huge deal if you’ve added racks and lots of gear. One thing it does not have is a kickstand or mounting bracket to add one. That sucks if you want to go bikepacking and are trying to put gear onto racks without having the already heavy 53 lb bike tip over. Again, I’m extrapolating here but the ample rack bosses suggest that this ebike is meant to carry a load.

Powering the bike is a standard Bosch Powerpack 400 rated at 36 volts and 11 amp hours. I say standard because Bosch now has a 500 watt hour pack that would take you further and be welcome for the rigors of soft surface riding with lower tire pressure or long steady climbs. Of course, those packs cost a bit more and the IZIP E3 Sumo is impressively priced at just over $3k. The battery interface remained the same from the Powerpack 400 to the 500 so you could always get one of the larger batteries later if you wanted. The battery case is thoughtfully designed with a handle loop at the top and an LED charge level indicator on the left. You can charge it on or off the bike and the charger is relatively lightweight at ~1.7 lbs and compact enough to toss into a bag. Rated at 4 Amps, it fills the battery faster than many other electric bike chargers which are only rated at 2 Amps. Charging the battery whilst on the bike requires the removal of a large rubber plug… which I love. It seats firmly and has several rows of ridges to keep water and debris out of the charging socket. The only downside here is if you set the plug down and forget it. There’s not leash or attachment to keep this plug with the bike and I feel like that’s a big tradeoff. Most of the other charge port covers on Bosch ebikes have a thinner rubber cover which do have attachments. It doesn’t get in the way and keeps the cover from getting lost… but those covers don’t always seat as well.

Operating the bike is intuitive and fast. Once the battery is charged and mounted you just press the power button near the lower left corner of the LCD display panel. This display is large, making it easy to read, and faintly backlit so it can be used at night. Unfortunately, you can’t turn the backlight off, it’s always there and in some ways that’s distracting. The bike doesn’t come with lights but some shops can wire them in and then you can use the Intuvia display panel to turn them on and off… Running lights off the main battery is favorable to charging and mounting them separately in my opinion but you could also charge a clip-on light with the Micro-USB port built into the right edge of the display panel. It feels like this display does everything. You can tilt it forward and back to reduce glare, remove it completely to keep it safe and deter tampering and you can even replace the display with the COBI system which uses your smartphone and offers even more features like GPS. Navigating the stock display is easy once it has been powered on. You can press the up or down key on the remote button pad which is mounted within reach of the left grip. Being able to add or reduce power while riding without taking your hands off is a great thing, especially for off-road riding. There are four levels of assist and the highest one will easily accelerate the bike to the top speed of 20 mph when on flat smooth surfaces. And while you only get five ticks to estimate charge level on the battery and display panel, there is another menu called range which dynamically estimates how far you can go and interprets it based on battery level, assist level and the last three miles of acutal ride performance. You can access this and other menus like average speed, max speed, clock and odometer by pressing the i button on the display or button pad.

The motor, battery and display panel on this electric bicycle aren’t as seamless and hidden as some others… partially because of their color and partially because they are larger and tacked on vs. built into the frame. But, they are a vast improvement over earlier designs and in many ways match the black tires, handlebar, and seat. Aside from the chain suck concerns I raised earlier, I feel like this is a really great bike. The price is impressive, the weight distribution is perfect and you’re getting high-quality braking and pedaling systems from leading brands. IZIP now sells online through their official website and fulfills using a mobile bike service called Beeline but it’s preferable to test ride in shops, especially to compare sizes, and they do have a solid network of dealers in the USA. I could see myself and friends riding these on long daytrips and possibly camping. It has the capacity to work with racks but does not include them stock like the Felt Outfitter. Hopefully, seeing that bike will give you some idea of what the Sumo could be with a little customization… The $2k price difference gives you a lot of wiggle room for customizing the bike and I think the Sumo has a much nicer motor and battery integration (though it is much newer). Apparently Felt used Old Man Mountain racks for their bike. Lots to consider, it’s a cool platform to say the least and I’m excited to see what people do with it. Big thanks to IZIP for partnering with me on this review and inviting me out to their headquarts in Simi Valley California to do some riding.

Pros:

  • Significant motor and drivetrain upgrades from prior model year, you get a wide-range 11-42 tooth cassette with Shimano SLX derailleur and a high torque Bosch Performance Line CX motor
  • Very few mid drive motors offer shift sensing technology but Bosch is one of them and it will reduce stress on the drivetrain, especially relevant for climbing and moving heavier wheels like the E3 Sumo has
  • The motor is tilted up and integrated into the frame more than some other electric fat bikes that use Bosch (or similar mid-drive systems), it has sleek casing on the sides and a metal skid guard on the bottom for protection
  • The battery pack is also neatly integrated into the bike frame with a flattened downtube and cup-shaped bottom… it looks great and frees up the triangle for lifting the bike and putting the battery on easier (since it snaps in from the top)
  • Lots of attachment option, there are five bosses on each side of the fork and two bosses on each side of the seat stays which could be used for outfitting this with heavy duty racks for bikepacking, hunting or other adventures
  • Deep angle on the top tube makes mounting and steadying the bike easier, it comes in two frame sizes for improved fit and handling for a range of rider body types
  • Impressive stock pedals, they offer space, stiffness, and traction beyond what I usually see and look great on the bike
  • Incredible price point given the level of components and Bosch drive system, it costs a lot to produce niche models like this and to see it in multiple sizes with such a cool aesthetic and quality hardware got me excited
  • Sturdy thru-axles keep the wheels stiff and can handle longer hubs (the rear is 190 mm long), punched-out Alexrims reduce weight and offer a bit more cushion on bumpy terrain
  • Narrow to wide tooth pattern on the chainring improves grab and reduces slipping,
    this is great for off-road riding
  • At this time, Bosch does not make a fat bike specific motor so IZIP had to really customize the frame with a narrower yolk that’s welded to the chainstays and an offset spacer on the left crank arm, it’s excellent engineering work and keeps the chainring aligned with the drivetrain
  • Large 180 mm hydraulic disc brakes with four-piston calipers deliver the stopping power you need for mountain riding and hauling heavy gear, the levers offer adjustable reach so you can bring them in if you’re wearing gloves
  • Both the battery pack and display panel are removable so you can reduce the weight of the bike for transport and store the sensitive expensive bits separately (inside) if you have to leave the bike somewhere else

Cons:

  • Despite having so many rack mounting points they were not able to squeeze in water bottle cage bosses, it appears that there just wasn’t room in the center triangle given the lowered top tube and on-frame battery pack
  • The four inch tires offer good comfort but we’re starting to see fat bikes with suspension forks and even full suspension, this isn’t so much a con as a consideration… the rigid alloy fork and solid frame won’t be as forgiving without suspension, consider swapping the seat post with a 31.6 mm suspension post like the Suntour NCX but note that it will raise the minimum seat height by a few inches
  • Keep an eye on the left crank arm and left chainstay because they pass very close and the Bosch speed sensor wire is run along the top of the tubing, if you’re riding in muddy terrain I feel like this area could get bumped around more easily (especially if you pedal backwards and aren’t careful)
  • I love the big rubber plug that covers the battery charging port on the left side of the bike but noticed that it does not have a leash to keep it with the bike when pulled off, it would be easy to set down while charging and forget… and lose
  • Watching the frame-mounted camera towards the end of the video review above, it looks like the chain may be sucked up after rotating through the chainring, I’ve heard this can be an issue when chains get really muddy but perhaps the NW teeth are causing it on this brand new demo bike?

Am dying to how this 10 Speed 1×10 Shimano SLX Derailleur, 11-42 setup would do if swapped for SRAM’s new EX1 system. I wonder if that is marketing hype or a genuine improvement over more gears (cogs, to be precise).

I don't want to be the one to say"you get what you pay for" but..... look at a bike with a bosch system; they make all the other stuff blush... and use a dealer...they will update the software when THEY build it and back it up..look at a Raleigh Magnus , Izip Sumo or a Felt lebowski .... on sale I see on their websites ..mid drive is a must !

I'm putting this bike back up for sale, as I need the money for a major car repair. 2015 Izip Sumo, have to check mileage later but probably around 100 miles on it, if that. Like new in every way, except for replacement suspension seat post-Suntour NCX. Rides great. Pick up only-Northeast PA, will not ship.
$1600 OBO.

I was blacktop bill, I some how screwed that up, forgot password or some thing. well turns out battery wasn't bad. I was checking voltage in the wrong place. At the bottom of the pack need to check at the charge plug. I'm lucky I bought the bike from a reputable dealer. They had the bike over a month before it was fixed. That's mainly because transx motor is none serviceable. Currie sold izip to Raleigh. Raleigh made bike shop tech check every possible connection and setting before replacing motor. Bike shop had to order gear puller to remove crank arms. It looks like a over voltage circuit was over heating. Probably a cheap fix if you could work on motor, Old motor had 600 miles on it when replaced, it seem to have a little more torque than new motor. Now that bike is fixed I have installed a wren inverted fork, I love the fork. Suntour ncx seatpost. 26 x 3 inch tires on the 80 mil. rims. Raised up the handle bars. the bike is a lot of fun, hauls my 250 pounds no problem. the only thing I would change is the 3s battery to 4s 0r 5s.

Addendum: my Bulls had maybe 120 miles on it at the time of this incident, so the chain was relatively "young."

Last year I had a chain break on my 2015 iZiP E3 Sumo (73Nm of rated torque), but it had a few hundred hardy trail miles on it at the time. I had to walk/coast the bike 3 miles that day...

I've since bought a chain checker tool and check my chains regularly. I also carry a quality multi-tool (with built-in chain-pin breaker) and the right size connector links for my chain with me on all my rides. Sure came in handy this time!

Chain breaks seem to be more common with my eMTBs - in ~30 years of "regular" MTBing, I don't remember ever breaking a chain! Of course, my bike weighed a lot less and my legs never put out this much force.

Same with my MTB-in over 25 years of solid riding, never broke a chain or had any major tune-ups or cable snaps. Just some lubing and light cleaning! A solid ride (Trek 7000 MTB American made in Wisc).

Looking as to where the freshest and least cost battery exists. Also here in NJ as to where to get one. And who can rebuild the original one for a spare. Expected costs. Optional increase in configuration like ah etc. is this something to consider or just stay with OEM?
Finally might consider just getting a new 2017 with Bosch motor style newer version of iZip or similar if a shop accepts trade in and offers a decent price.
Sooner than later replies would be greatly appreciated. Existing battery is fine it's just that I'm approaching 2 years 4000 miles and although I've replaced the tires casette and chain I'm wanting to be pro active rather than reactive.
I searched all over the internet and it is very hard to get IZIP OEM replacement battery, not until most recently. It is also a proprietary battery with different voltage output at different pins. So those generic batteries won't work. I read somewhere that a guy used a generic battery but the PAS control does not work and the display does not work. For me, to keep my ebike working like new, I had to use OEM battery, and am glad that's what I did. The battery is priced at $599.

It is priced more expensively at other sites.

Last year There was none available but I was able to negotiate with a store in California to buy the battery from an Izip displayed on the show room. Later, I also purchased a highly discounted Raleigh Tekoa with the same battery. Now, I have 2 ebikes that share the same battery but 3 batteries all in all.

James Kohls, you make many good points, specially regarding the value of local dealer support and regarding exercising caution with the new HyperFat until other users have uncovered its bugs.

However, I have to disagree with your statement: "But there's nothing stopping you from adding [a suspension fork] later." If the frame geometry is not "suspension-corrected", adding a suspension fork may make handling squirrely. I don't know if the iZip E3 Sumo has a suspension-corrected geometry, but I would definitively ask the manufacturer before buying an aftermarket suspension fork.

Some manufacturers, such as Surly, make a point of noting which of their frames is "suspension-corrected." Unfortunately, Surly does not make any ebikes (I wish their Big Fat Dummy was an electric bike!). As far as I know, no manufacturer of ebikes tells us whether their frames are suspension-corrected. You either get them with suspension or you don't. (Anybody, please correct me if I'm wrong.)

"Suspension corrected geometry"

This would be important if you add let's say 120mm travel fork on a bike that is only designed for short rigid fork. Frames that are designed with this "correction" would yield no significant difference in handling even if you change out the rigid ones for a longer suspensions.
Most rigid forks are shorter than suspension forks and to offset this, manufacturers like Salsa, Surly have released frames that can accommodate certain changes without making the bike too squirrely. In fact, you can even find "suspension corrected rigid forks" that are longer than the typical rigid forks.

Also, running BBS-HD in conjunction with a powerful hub motor would be completely unnecessary and heavy. Tora designed the frames in such a way that you can simply remove the rear wheel and install a BBS-HD and plug into the same battery if that's what customers prefer.

Juiced bikes has certain advantage compared to all other brands because they make their own battery packs and enable 8-10A charging , modularity and upgradeability.
PS: I spent insane amount of time last fall figuring out how to add RockShox air fork to Haibike SuperRace w/o ruining the nimbleness.

Thanks @Bicyclista. Speaking from my own ignorance there. I was not aware of suspension-corrected frames. I heard Court mention adding one in his 2017 Sumo review (he didn't specifically say you could properly do so—only that some may want to).

Yes, our selection of eBike dealers in Minnesota is pretty thin. Those that do sell eBikes rarely carry much stock and often means you will still have to buy sight unseen. I am personally considering the Specialized Turbo Levo HT Comp Fat that @Ravi Kempaiah mentioned. It is among my top contenders because it can handle very wide tires. Tho, I saw that @racer83l was able to fit 4.8" Jumbo Jims on his Rad Rover. But cadence sensing is just not for me.

Your desire for a throttle probably means sticking to Internet online brands as most major brands that stores carry around here are all switching or have switched to mid-drive setups without throttles. The Juiced HyperFat is interesting, but for an online bike, my personal thought is to wait until people have had them for a while. See what bugs crop up after wide release. Given its option for a torque sensor, it would by my recommendation given your preferred budget.

Speaking from experience, I do think that local dealer support and repair is worth a significant chunk of change. Thousands of dollars more? That's up to the individual. The biggest concerns I have with purchasing an eBike from an online dealer is support for proprietary components—basically, the e-part. Typically these companies handle electronic repairs via mail. May want to check with owners about who pays for return shipping of damaged parts (and if they require such thing). This would also place you on the hook for replacing them—something that depends on your comfort with such things. Most I've seen don't appear overly complicated.

One that may be of note, that is available from Eric's Bike Shop in MN, is the iZip E3 Sumo. The 2015 model has a throttle and is technically a speed pedalec. Downside to your wish list is no suspension fork. But there's nothing stopping you from adding one later. Maybe the big fat tires will be sufficient for your needs. Uses TranzX mid-drive and is on closeout for $2399.

Or there's the new Bosch center drive (no throttle) version for $2899.

If you live in an Eric's market, you'd have local dealer support.

Edit: In a month or two, they'll be releasing the Raleigh version of the Sumo. Not sure if it will be $2899 like the Sumo or the MSRP of $3199. (Starts @ ~1m29s)

Bob, its "under power and slow," = lack of power with any grade over 10%, we spent most of our time riding in mountain in So Cal. The Brose below 10% rides like all of them, but anything over 10%, the Brose is a dog, anything over 15% be prepare for a workout, over 20%, you better be running a 36t in the rear. In the mountains, we rarely go past 12-15 mph on single track riding, but in certain areas it requires torque to get you out, there were it lacks the power.

Brose stealthy look is my favorite, out of the Big 3, but torque power is my least fav....
My Bulls...FS3 Plus, rated at 90Nm, has at least as much torque as my 80Nm Yamaha-powered SDURO AllMtn Plus, and both eMTBs climb 20% grade hills with relative ease. The Brose motor's definitely more subtle, with its peak power coming at lower cadence than my Bosch, but I've yet to experience a CX. The Yamaha also seems to peak at a lower cadence than Bosch.

FWIW, I posted about a broken chain experience I recently had with my Bulls in its first 120 miles or so, which I believe was caused by large chainring to large sprocket cross-chaining. My concern is that, when the chain broke, the Brose motor spun furiously fast, making a horrible, very high-pitched whining sound for several seconds. I've broken a hi-torque ebike chain before (on my 2015 iZiP Sumo), and its much lower-tech TranzX motor shut right off.

The fact that the Brose kept spinning makes me worry about the long-term - it rode fine after we fixed the chain but it was an AWFUL sound! Barney's put in a query with Bulls' Germany HQ because he's never heard of this happening.

Jim= I have had my MTBs for over 25 years (Trek 7000-Made locally) and have never had a chain snap! Lucky I guess. I have always cross chained with no issues.

no tested torque, top speed, time to speed, or real world range. Time to charge. Recommended maintenance. How well does it coast. Problems reported by owners and dealers.
No basics, so, finding all these reviews totally missing and useless, I had to go to my dealer and ride 12 different bikes before deciding on my kalkhoff. Also he's not talking to dealers about reliability and support, which is how I decided on mine vs Stromer. I learned Curry (aka iZip) provided excellent dealer support, even breaking down a bike for a dealer, calling that dealer, and reporting wiring info to that dealer, to solve a throttle problem for the customer. But I'm no expert and don't know about Haibike, ESV, Reise and Muller in these respects.
Real world wise, "color schemes" aside, I had to spend two afternoons at my dealer really learning about OBJECTIVE PERFORMANCE because these videos are really useless. Especially mounting a camera on the chain stay and filming a ride. What on earth does that show or prove.

I don't mean to be hating but 36 V how long will that last you in the real world looks great in the parking lot for 10 minutes how well can it really climb ? And for how long ?

ElectricBikeReview.com

Hi Karl, in my experience the 36 volt system is extremely capable when used on mid-drive ebikes. Bosch, Yamaha, Shimano and Brose use this voltage with varying amp hours for larger or smaller watt hour capacities. I'd look at the torque rating for power and amp hours for range and go higher if it's a mid-drive. This model (with the fat tires) might get slightly less range... but if used on packed flats it could still top 30 miles per charge on the mid levels of assist. The highest level might only get 20 to 25 depending on terrain. Hope this helps!

I'm not very keen on that offset motor and the special left crank pedal. If you decided the crank length was not good for you can you easily get alternative lengths?

ElectricBikeReview.com

I believe the cranks are a bit longer on this model, 175 mm vs. standard 170 mm but the width is probably also slightly more. To me, it felt great... you could probably change the crank arms but not the width of the stance
