Written Review

The Spark is a powerful, well-balanced, cruiser style electric bike built around a sturdy high-step cantilever frame. Motiv produces a very similar model called the Sleek which is slightly smaller and offers a lower stand-over height. Both models are made primarily from Aluminum alloy but feature a vibration-dampening steel fork and full steel chain cover. Rather than weigh the bike down and increase the cost and complexity of the product by adding a suspension fork, Motiv opted for a lighter suspension seat post, padded saddle, and swept-back handlebars. These, combined with the wider 2.35″ Kenda Small Block Eight tires (which have a decent 30 to 50 PSI range), deliver a fairly comfortable ride. Not much has changed on the Spark since I reviewed it in 2013… the price has dropped slightly and you now have four battery size options. The display changed from a simple three-color LED indicator showing relative battery capacity to an advanced LCD display that gives you more control over speed settings. The 2017 Motiv Spark offers basic cadence sensing pedal assist as well as a variable speed twist throttle. The two systems complement each other perfectly, offering riders a way to start from a standstill, pedal comfortably with a bit of help, and override assist instantly at any time to maybe climb or catch up with a friend. You can get the Spark in a wide range of colors, and I found that they were unique and nicer looking than the standard primary red, blue, yellow etc. Some, like the black model shown in the photos and video of this review, are matte and others are metallic.

Driving the bike is a 500 watt nominally rated Bafang geared hub motor. I’m told it can peak over 900 watts and I believe it… especially on the 48 volt battery version of the Spark. This hub motor is compact, responsive, and it blends in with the black spokes if you go for the black frame. These days, a lot of ebikes are hitting the market with mid-motors but they usually don’t have throttle operation, they tend to cost more, and they complicate the drivetrain (often straining the chain, rear sprockets, and derailleur. What you get here is a time-tested system that’s a bit less efficient, but easy and enjoyable to use. Note that the front wheel has quick release while the rear does not. It uses nuts (as most hub motor setups do) and the axle is slightly thicker. As far as pedaling goes, you pedal completely independently from the motor and have six gears to work with. It’s a rather small range but much better than a single speed as some cruisers offer… at least for climbing and being able to catch up at high speed. Sam Townsend, the owner of Electric Bicycle Center in Fullerton, was on hand for this review explaining that some of his customers upgrade the chainring or cassette to have a wider range because they will adjust the speed settings to go over 20 mph. At and above 20 mph, the stock setup has your legs turning a little fast, so I get that. Derailleur used here is a base model Shimano Tourney TX and the shifter is a large thumb style setup that works well if you’re wearing gloves but is more difficult to reach while gripping the bars than trigger shifters, in my experience.

Powering the bike is one of four battery pack options ranging from 36-volt 11 or 16 amp hours up to 48-volt 11 or 16 amp hours. There’s a noticeable difference in torque and power with the 36-volt options but they weigh a bit less and also cost less. Note that you cannot switch from 36 volts to 48 volts once you by the bike, the power system is different… so, unfortunately, it’s not like you can upgrade the battery pack down the line even though they look the same. With a 48 volt system, you get more efficiency in power transfer and a higher watt-hour capacity for longer rides. If you’re a larger person and don’t intend to pedal much, I’d definitely consider the 48-volt upgrade. I like how the battery is positioned on the bike, low and center, and that you can remove the pack and easily carry it around by the plastic swivel handle up at the top. This is a Silverfish battery pack design that has been around for many years, it’s the kind of part that is shared across a range of e-bikes and can be replaced or repacked more affordably. The one gripe I have is that you have to insert, twist, and leave the key in the battery pack in order to use the bike. It functions much like a car ignition in this way… and I find that the key is more prone to snags and jingling if you also have a keychain connected to it. If you just leave the key on its own, you might have to take it off every time you stop and that’s a hassle. Most electric bicycles these days only use a key to lock the battery to the bicycle and then use a power button in place of a keyed ignition. Thankfully, the battery can be charged on or off the bike and the standard 2 Amp charger is fairly portable.

Operating the bike is fairly easy and you get a bunch of customization options through the LCD display that other e-bikes just don’t offer. So you charge and mount the battery, turn the key in the battery to on, then press the MODE button on the button pad near the left grip for a second or two. From here, the display flickers on with standard readouts like battery charge level, clock, assist level, speed, and odometer. You click the up button for more power and the down arrow for less but the twist throttle is always active and provides full power if you twist it all the way. This is an important point because it’s easy to end a ride and get off the bike but forget to turn it off… and then bump the throttle and have the bike lurch forward. So back to those options, you hold the up and down keys for a few seconds together to enter settings and this is where you can raise the top speed, change the units, and even adjust the number of assist levels from 5 to 3 if you prefer less button pushing. You don’t get a fancy USB power port on this display combo and the battery infographic is a bit limited with just four bars vs. 5 or 10 or a battery percentage, but it’s still an upgrade from the older 3-LED design. The cockpit area of the Motiv Spark is wide open and fairly clean. I like the brake levers they chose because the leading edges are rubberized and there’s an integrated bell on the left. There’s plenty of room to mount a cup holder up here, which is great because the bike doesn’t have bottle cage bosses. You could also add a disc brake compatible rear rack.

All things considered, this is a more basic electric bike that uses the same hardware you could buy in a kit and mount yourself… but the price isn’t that bad and the frame is purpose-built with additional strength and internal routing in areas to clean up the look. For 2017, Motiv changed their cadence sensor to be smaller and more protected. You get rear rack bosses and could certainly add fenders aftermarket (in fact, I think their latest models may come with them). I appreciate the large mechanical disc brakes and am willing to trade of hydraulic for the cost savings here. The founder of this company is a cool guy and I just like the way the product looks. If you’re someone who appreciates the OC So-Cal chopper look and wants a powerful throttle operated electric bike, this is one of the best options. There are groups of Motiv owners who go on rides together and I feel like it connects with a certain type of rider. It’s definitely a capable bike, though a little less refined than the $3k+ models we now see from mainstream manufacturers. I appreciate the upright relaxed feel and serviceability of the design.

Pros:

  • Even though this bike doesn’t come with a suspension fork, the steel fork dampens vibration, the larger knobby tires take out small bumps, you get a seat post suspension to ease your back and neck, and your body position is a bit more relaxed thanks to the swept-back cruiser-style handlebars
  • Excellent kickstand placement, it stays out of the way and makes servicing or cleaning the chain easier because you can pedal backward with it deployed
  • Comfortable oversized saddle and large grippy oversized pedals, The touch points are solid and this makes pedaling and just handling the bike a lot easier
  • Lots of battery options with this electric bike, you can optimize for affordability or power and range, the 48-volt packs are more efficient and provide a zippier feel
  • I love that the battery is positioned at the center of the bike vs. a rear rack, appreciate that all of the different sizes of packs still use the same casing and fit in the same spot, and that you can charge the battery on or off the bike, it makes parking easier and makes the bike lighter for transport as well
  • The Promax brakes have tool-free adjustable calipers, large 180 mm rotors, the levers have motor inhibitors, and there’s an integrated bell in the left lever that sounds loud and clear
  • The wheels are built with thicker 12 gauge spokes to handle the high forces of the hub motor and potentially, a heavier rider or load if you add a rear rack
  • For a cruiser bike like this, where you might have the saddle low and relaxed, it’s great to have twist throttle because pedaling might not be as comfortable, so it’s great that you have assist and throttle that overrides assist to help you get going or zip all the way up to full speed
  • Motiv is using a new, more compact, cadence sensor that is less likely to get bumped out of alignment or become inconsistent due to dust and dirt, it worked really well
  • During the video review, Sam Townsend of the Electric Bicycle Center in Fullerton started telling me about rides he had done on the Motiv Spark and what accessories he likes which included the Topeak Disc Brake Rack and Slider Trunk Bag
  • The display panel is an upgrade from earlier Motiv electric bike models which just had a three color LED readout for battery level, you can adjust a lot more now including the top speed by holding the up and down arrows for a few seconds to enter settings

Cons:

  • Only available in one frame size but you could opt for the Motiv Sleek which is basically the same e-bike, just in a step-thru design, both models come in a wide range of colors
  • The bike doesn’t come with any fenders, rear rack, or integrated lights, but it’s priced lower and does have provisions for adding your own, I like that it has a full chain cover but wish it had bottle cage bosses
  • Some of the wires aren’t internally routed which doesn’t look as clean and could snag easier, but some shops have told me that they prefer working on bikes like this because it’s easier to access parts
  • In order to operate the bike, you need to insert the key into the top left side of the battery pack and turn it like you would with an automobile, this leaves the key a bit exposed to bumping or jingling around as you ride (especially if you have it on a keychain)
  • More basic drivetrain, you only get six gears and the derailleur is the lowest part level in the Shimano line, Tourney TX
  • Sam told me that you can ungovern the motor to ride a bit faster with the help of your shop, and in that case, you might also want to upgrade the drivetrain to have a larger chainring or smaller sprocket at the rear so you can keep up and not be “beating eggs” pedaling so fast
  • Because this bike uses a cadence sensor vs. torque or combined signal, the motor takes a moment to kick in and then drop out as you stop pedaling, this is where the throttle and motor inhibiting brake levers become useful

Another update and another delay (once again due to improvements to the design):

Hello ShareRoller Indiegogo backer:

We've made a LOT of progress since our last Update, but unfortunately have also encountered a few unanticipated delays. We'll try to share as much color as we can below so you understand both our challenges and accomplishments.

So we're nearly ready to begin assembly of the first 150 unit batch of the new ShareRoller SR4. Our team of suppliers (we have 7 different suppliers!) has been manufacturing the first batch of SR4 subcomponents since early May, and first shipments (of subcomponents) should be going out any week (we've learned that 3-4 week production estimates seem to become 4-6 weeks+ as standard practice..)

Nevertheless, here's what's ready to ship from our suppliers imminently:

- Drive Motors: We've talked a lot about these before, so you know how amazing they are - we can't wait to have hundreds of them sitting on our assembly floor!
- Custom urethane Drive Belts: We've had to go through several iterations of molding to get the fit just right on these, fortunately it's a quick turn-around so they're fully sorted.
- Heatsinks: If you recall in our last email we talked about our solution to improve motor cooling, well here it is: Dual heatsink mounting plates for the motors. We had to build molds for diecast aluminum to make these cost-effectively, which takes a LONG time, but they're done now - and here's a picture of the first sample diecast parts:

- Gearmotors: We haven't talked much about these yet for IP reasons, though if you search our patent filings you'll find a reference to them... Custom ultra-small, ultra-high torque gearmotors to continually manage normal force for our Automatic Traction Control system (both under power and while braking), and to lift the motor clear off the tire when you don't need it. Our supplier has been making these for over 6 weeks now, and they're due to arrive in NYC any day.
- Wireless throttles: We've got a great custom design perfected now for our wireless custom throttles, with custom PCB production underway. Not only do they give you proportional control of both throttle and brake, but they also have secondary buttons for operating TailWind or PAS settings. Plus a rechargeable battery that seems to last days. And a really cool spring-clip mounting system with ball-joint pivot that allows you to mount the throttle almost anywhere on a bike or scooter and still find a comfortable position.
- Retracting battery cables: After our earlier quality issues were solved by upsizing the housing, our manufacturer is currently assembling our first production batch as quickly as they can. These required custom injection mold tooling, which means a 6-8 week leadtime, but they should be done in another two weeks.

Unfortunately, we have two components that are further behind schedule. Our custom PCB and our custom Battery Packs. These two components are a big piece of what makes the SR4 so special, which is a good thing given how much work they've required!

To be clear, we already had a first version production SR4 PCB several months ago and it worked well, with both the wireless throttle and phone app functionality we dreamed of. But we needed to add a few more pieces of critical functionality to it:

- Inrush current protection (aka 'Anti-Spark'): this is necessary to prolong the life of our magnetic battery connectors, especially at the higher voltages the SR4 uses.
- Onboard DC gearmotor control: we had been using a standalone board for this, but for reliability and ease of assembly it made sense to integrate it

Both of these circuits are relatively large, and since we had no more room to make the PCB any bigger, we needed to redesign it using surface-mount components (SMT) to shrink every section. This is a lot of work and has taken longer than expected, but we do expect to have production PCBs completed within 3-4 weeks, so this won't be the biggest holdup....

Which brings us to our custom battery packs, the most delayed of all our components: We can't begin to describe how involved the design and manufacturing process has been for these. With nearly a dozen different molded parts, a custom-designed Battery Management PCB, soft power switch, USB charge port, LED indicators, and the aforementioned retractable battery cable, this by itself is probably more complex than many hardware products in their entirety. But with ShareRoller's unique versatility and portability, an existing 'off-the-shelf' battery pack just wasn't an option.

Since we haven't shown the battery packs in detail yet, here's a teaser pic of our unique 'Multi-Mount' attachment system (on a 'Mini' pack) - believe it or not, both the mounting brackets needed for bike share use and personal bike/scooter use are contained in the folding, modular mount shown below:

The other completely unique part of ShareRoller's battery packs is our 'Versa-Handle,' which does double duty as both a carrying handle and as a locking mechanism for bikeshare use. Here's how it looks extended for transport (You can see our LED battery gauge here too, and yes that is brushed aluminum for the handle!):

We've had 'near-final' designs settled upon month-after-month for these packs, since as far back as March. And every time, it seems a new subtle tweak is needed to meet the complex demands of either our custom housing, electronics, mounting system, or unique multi-purpose handle.

The good news is that after 7 months of relentless back-and-forth CAD iterations with our supplier, we've finally resolved all design issues, signed a Molding Contract (in Chinese!) and wired a sizeable tooling deposit, so they are officially underway. Unfortunately, it will take 4 weeks to complete the molds, and another 2-3 weeks after that before packs are assembled. We also need to complete UN38.3 certification (required for air shipment), but the plan is to do that in parallel with volume assembly.

Given all of that, we don't expect to have production battery packs ready to ship before early-mid August. Fortunately, there's zero assembly required for the packs - they arrive turn-key. So we can assemble everything else in advance, and ship out complete ShareRoller SR4 boxes the moment the packs arrive.

We're deeply sorry for these continued delays and we really wish there was some way we could deliver sooner. We understand how frustrating it is to still be without ShareRoller power, especially as Summer unfolds. Unfortunately, many factors are outside our control here, so all we can do is just continue to push relentlessly to be sure the ShareRoller SR4 we finally deliver will perform beyond all expectations, and at least in hindsight make it all worth the wait.

Thank you so much for your patience and support.

Hi, this is Ron/spinningmagnets. I try to be as independent as possible, and to write information to help the average guy, because I am an average blue-collar guy. Bosch/Yamaha vs BBSHD...whats my opinion?

I have ridden a Bosch, and also the Yamaha (at two Interbike conventions). If you like that sort of thing, save a few bucks and get the Yamaha. I don't hate on the Bosch, but they charge a premium just because Europeans have a bias towards German products over Japanese. If you own a Bosch and are happy with it? sweet...let's ride together and have fun on a beautiful spring day. When armchair mechanics argue, it's just another Ford vs Chevy crap-fest.

Are you foolish for buying an expensive Bosch / Yamaha? No...there is a market for that. If you like it? Be happy, and don't waste time with regrets. That being said...I can afford anything I want, and my most often ridden ebike is an Electra stretch cruiser with a BBSHD. I went with a 52V battery pack because, the stock controller will work with 48V or 52V. A nominal 60V battery can produce a spark that can penetrate dry human skin, but 52V? no. I literally wrote the article on electricbike.com about benefits/drawbacks of a 14S pack.

If a friend of mine had to make a choice between a small 52V pack, or getting a much larger 48V pack? I'd say get the larger pack, there are a lot of reasons a bigger pack (regardless of vendor) is better for the owner. That being said, I own a very large 52V pack, and I can afford as many watt-hours as I like.

Bosch and Yamaha drives are very sophisticated and they are very similar. They take a small amount of input watts, and turn that into as much wheel-torque as possible. It is accomplished in a very smooth and sophisticated way. This is like the Mercedes, Porsche, BMW market...when they sell a 4-cylinder car (which they have done). Its nice when they are new and under warranty by a local shop, but...if you buy a 5-year-old one? what can an average blue-collar guy do to hack a cheap used 5-year-old M/P/B car?

I am an old gear-head (58-ish), and as a much as I appreciate a sophisticated aluminum 4-cylinder turbo 4-valve engine with EFI...when it comes to buying and wrenching on a motor? the BBSHD is the Chevy 350 of the Ebike world.

Use a thermal IR camera on it...it is not even breathing hard at 52V X 30A = 1500W. I would not run it at 3000W, but...it has been verified to run at 52V X 50A = 2600W, or...72V X 35A (using an external controller)...so...the mechanical portion of the drive can sustain 2600W. Will it wear out faster than when it is run at 1500W? If you ask that question, then...you don't understand what is going on.

If a certain customer is like an engineer, and he wants decent wheel torque at the lowest possible input watts...get the Yamaha mid drive. If you want LOT of fun, and you also want the ability to upgrade your fun-result in the future? Get the BBSHD. Also, get a spare primary reduction gear and a tube of high-quality grease, because...I am going to beat on mine like it is a rented mule. Try 2600W on a cheap drive unit and then tell me that it doesn't put a freakin smile on your face...
I had hoped there would be a post revealing the facts that this isnt just a blue collar poster, rather an employee of Lunacycle and paid writer for electricbike.com. Hardly independent nor impartial. Always a good read but not always forthcoming.

Hi, this is Ron/spinningmagnets. I try to be as independent as possible, and to write information to help the average guy, because I am an average blue-collar guy. Bosch/Yamaha vs BBSHD...whats my opinion?

I ride technical trails on a regular trail bike (Giant Trance X 0 29er). I love the bike. I would also like an e-bike with the most trail capability.

My only experience is that I converted an old hard-tail to an e-bike with a 1500 watt pedelec hub-motor and 1000 wh battery behind the seat, and it was fun on the street, but it was terrible on trails. Unridable really, due to the weight and balance of the battery and motor. Also, the direct drive would not be good for off-road climbing. Battey and motor should be mid-bike and as low as possible, and battery should be about a 500 wh. I sold off the parts.

So I have decided a few things that I want in my next e-bike.

1. Must have a mid-drive - like Shimano, Yamaha, Bosche, or Brose.

2. Must have stealth look with well integrated motor and battery.

3. Must have torque-sensing and a pedal feeling be as transparent as possible without awkward surging.

4. 250, 350, 500, or 750 watts are all ok. I don't mind at all if it is 250 as that will be lighter, save battery power, and I am happy to pedal.

5. 15 or 28 mph are both ok. I would prefer 28, but not if the bike is worse in other ways.

6. Prefer compatibility with 3.0 inch tires (650B+).

These are the bikes I have found so far that look like what I want, but I have not ridden any of them. Which are the most trail-capable and have the most natural pedal feeling?

Giant Full-E+
Haibike XDuro NDuro Pro $5,800
Lapierre Overvolt AM 900+ £6400
Moustache Samedi 27 Trail Limited £7600
Nicolai ION EBOXX
Rotwild R.X+ FS €6,999
Scott E-Genius 700 Plus Tuned $5,400
Scott E-Spark 700 Plus TUNED £6,099
Specialized Turbo Levo FSR (Four trim levels - $4500 to $9500)

A real Mtn biker with real Mtn bike tastes. The demands of the trail are real and forth telling. A cheap trail or mtn bike will not perform or last. Same thing applies to MTN ebikes. The extra weight demands higher end and rugged components. For 2-3 lbs, sacrificing weight for strength is my motto. Go for lighter/small battery and stay 350 or less watts when riding to support a good hour ride, but less weight.

Eddie recommend KTM, but he is in Britain.

Hi there,

Update, never mind, the vendor will replace the controller :-)

Got this brand new 48v e-bike with integrated headlight. On the first ride at night, the light worked fine for 10 minutes. Then after some bumps, it started flickering and turned off. The positive connector got loose during shipping and had unplugged itself. So I reconnected it, but forgot to turn off the power. There was a very tiny little spark when the wire touched the lamp connector and it stopped working.

So i thought I fried the headlight. The vendor thought so as well. I went to see him and my original headlight works fine when tested on other identical bikes. He still gave me a new one, got home, tested it, still not working.

I don't know much about electricity but can tell you this:
- on a voltmeter for DC voltage,
I get 35 volts at the headlight wires with bike and light turned off (!!)
35 volts with bike ON but headlight off
and 27 volts with bike ON and headlight on.

this makes no sense to me!
I then exposed a bit of the headlight wires, plugged in the light, turned it on, and now I get only 3volts, which explains why it does not work

Any hints on what is going on and how to fix it or troubleshoot it further? thanks for your help!

We love our Motiv's just did a memorial day weekend trip to Palm Springs with some customers had a blast. The Motiv bikes have never let us down and we have logged more miles on the them then any other model of E-bike we carry. The newest container of bikes from Motiv now come with color match fenders and integrated headlight with a solar powered tail light. Here's the best news of all, To be more competitive with the competition the Wholesale price has been lowered to the dealers.

I know the optimum place for the battery is forward of the seat down bar, but for me this is the best. it's out of the way of both your feet/legs and a rack. plus, the battery here is more protected in the event of a spill, AND still accessible. it also allows the engineers to play around with more aesthetics in the rear of the bike. no wonder they sell a bunch with the motor specs- like it, GREAT starter bike price wise as well. nice review for a beginner I guess...
