Summary:

  • A value-priced urban electric bike that includes fenders, integrated LED lights, a rear rack, and hydraulic disc brakes, it’s available in three frame sizes but only high-step
  • This is a high-speed Class 3 ebike that can reach ~216 mph assisted and because it relies on a cadence sensor, you don’t have to push as hard to get there, excellent weight distribution
  • Custom frame with internally routed cables and a bottle cage mounting point, turning the bike on and off requires extra steps, the display panel is not removable

Pros:

  • This model has long been a favorite electric bike model for me because the price is reasonable and you get a lot of useful accessories like fenders and lights, this model is a Class 3 speed pedelec so it’s useful for commuters who need to get to work quickly
  • This model uses a CAN bus system that allows the different electronic components to communicate with each other, making maintenance much easier for shops because the system can tell if something is wrong
  • The display has deeper settings which allow you to raise or lower the amperage which increases or decreases the feeling of power (and in turn, uses more or less electricity from the battery)
  • Considering that this is a speed pedelec, it’s great to see a suspension fork with decent travel (65 mm) and it’s an air fork so it doesn’t raise the weight of the bike very much, it can be locked out
  • The Kenda tires are wider than road tires which improve traction and increases air volume for comfort… but they run at a higher PSI which means that you might want to swap the saddle or add a 31.6 mm seat post suspension to further improve comfort
  • Being seen is increasingly important if you ride on streets with cars frequently and since this is designed for urban environments, I love that they went with a red paint color and have integrated front and rear lights (the headlight has windows on the side so you can be seen easier as well as see where you’re going)
  • The bike comes in three different frame sizes to dial in fit for a range of riders (tall or short)
    and the top tube and seat tube are fairly low for a diamond “high-step” frame
  • Because the motor controller uses cadence sensing instead of torque, you don’t have to push very hard to get it going but you might not get the same range and fluid feel that some other ebikes offer… it’s a trade off but their system works pretty well
  • I like that this model is offering a 10-speed drive train here given the wide range of speeds (up to 16 mph assisted) and that the chainring has an alloy guide to reduce chain drops and keep your pants from touching the chain
  • Excellent frame balance with both the motor and battery positioned low and center, this improves handling and since the battery is removable it also makes it easier to mount on center-hang racks
  • The center of the frame is fairly open and they managed to squeeze in a pair of bottle cage bosses along the seat tube, so many ebikes (especially mid-level products) don’t have these and I find them useful for fluids, mini-pumps, and locks
  • The optional rear rack uses standard gauge tubing and should be compatible with a wide range of trunk bags and panniers, the fenders look great and offer good coverage, and I love the kickstand choice and mounting position because it stays clear of the pedals
  • I like that the battery pack has a sort of built-in handle at the top so you can carry it more securely, this is useful if you bring the pack inside to charge during the day if you work in an office etc.
  • At ~53 lbs with the battery, I would consider this to be a relatively light weight electric bike because it does have a suspension fork, fenders, alloy platform pedals, and a rack
  • Both wheels have quick release and the drivetrain is not changed by this being an electric bike (the way hub motor powered ebikes are) so you can do maintenance and change flats a lot easier, shops may feel more comfortable working on this bike as well
  • Custom tubing work with internally routed cables and some extra supports at the base of the battery mount, it looks very nice and I like that the battery slides out from the side vs. clipping-in up and down because you’re less likely to bump the frame when mounting/removing it
  • The rear wheel uses a 12 mm thru-axle that’s stronger and stiffer than a standard 9 mm skewer and I noticed that the spokes are slightly thicker as well, 13 gauge
  • One of the menus in the display panel is range estimate and I think this is much more useful than the five bar battery infographic, it’s cool to change power levels and see how it impacts range on the fly
