  • A folding electric bike that’s fairly lightweight at ~41 lbs, clean and simple thanks to a Gates Carbon belt drive, and still feature rich with fenders and integrated lights
  • Available in two color choices, offers pedal assist and throttle on demand, highly adjustable extra-long seat post and telescoping stem, comfortable saddle and grips
  • Solid mechanical disc brakes with motor-inhibiting levers for safety, relatively easy to fold (in part because it’s lighter), hidden battery and compact motor look nice
  • Single-speed makes starting slow so having a throttle is very nice, non-removable display is beautiful so be careful not to scratch when folding, no suspension features but the fatter tires reduce vibration and bumps


  • Very few electric bikes come stock with the Gates Carbon belt drive but it’s an awesome feature, lasting longer than a chain, weighing less, getting less dirty, being less likely to fall off because of the CDX center-track design
  • Plastic fenders keep you dry and clean, the flexible rubber mud flaps won’t get bent, cracked, or rust the way that metal ones would, which is nice when folding or riding over tall obstacles like curbs
  • Two integrated LED lights that run off the ebike battery improve safety and convenience, they won’t get left on accidentally or be as easy to steal as aftermarket lights, the reflective tires further increase your visual footprint
  • I personally think that this folding electric bike looks great, the battery is integrated and protected inside the frame (also keeping weight low and freeing up the rear rack for cargo) and the hub motor is compact and almost hidden between the cassette and 160 mm disc brake rotor, you also get two color choices!
  • Kocass offers some of the best customer service in the industry based on what I hear and have experienced as a customer when they were just getting started in 2013, you get a 2-year comprehensive warranty, a sliding-scale battery replacement plan, and they now have a factory shop in Seattle where you can take test rides
  • The display is large, bright, colorized and easy to read, I love that it shows battery percentage vs. just a 5-bar infographic and that it changes to a dark background when the lights are enabled (to reduce distraction) the motor control system offers both pedal assist and throttle on demand so you can get started from stop signs and traffic signals easily vs. always having to push
  • It’s very common for folding electric bikes to weigh as much as a full sized ebike, so I was excited to find out that this one is only ~41 lbs vs. 50+ lbs
  • The frame is very purpose built with protective cable housing and good weight distribution front to rear, the front wheel offers quick release but they sell locking hardware for people who are worried about theft
  • I love that the display has a standard sized USB port in addition to a second USB port on the battery pack! This means that you could charge portable electronics while riding and use them up at the cockpit without a lot of extra cable mess, but you could also use the battery pack as a backup power source off of the bike
  • In addition to the integrated lights, reflective tire stripes, and standard plastic reflectors in the pedals, I like that the bikes come with a flick bell for signaling in a friendly way
  • Minor pro here but the bike seemed slightly easier and simpler to fold than some competing models, I love how the seat post supports it and protects the chainring with plenty of room to spare
  • Kocass sells a few optional accessory packages and I LOVE the trunk bag option, it has reflective fabric and fold-out panniers for those times when you really need extra space… the bag is awesome and works perfectly with this smaller rack design, full sized panniers may hang down and rub (though I have not tested them)
  • I feel like Kocass found the perfect balance of control and safety with their throttle design, it is not active at assist level zero or when the brake levers are pulled, you can only activate the throttle in 1-5 assist and the trigger is mounted near the right grip (which feels natural for me as a right handed person), it’s still a good idea to always shut the bike off before folding or mounting/dismounting just to be safe
  • Even with the fenders and rack, which sometimes rattle on electric bikes, the Kocass Quest rode very quiet, even across the bumpy grass sections we tried
  • The extra-long seat post and telescoping-height stem make this a suitable platform for a wide range of riders (even though it only comes in one size option), it felt solid and stable to me (even when riding one-handed and filming)
