Overview
Commuting on paved streets is the job of this Gotrax Dolphin, a step-through electric bike with an aluminum and ABS frame. A rear Shimano derailleur, a trigger shifter and a rechargeable battery are fitted.
Pedal-assist and throttle on demand give two ways to ride, and the front suspension takes some of the sting out of rough pavement. The step-through frame makes mounting easy. The limitation is the stated use: it is built for city terrain, not trails.
Who it's for
Adults and taller teens riding urban routes who like a step-through frame and a motor that helps on hills. Off-road riders, shorter riders and people unable to assemble a bike will want a different option.
Pros and cons
- Pedal-assist plus throttle
- Dual disc brakes
- Built for pavement only
- Peak and rated power differ
Performance notes
The motor adds force when the rider pedals, and a throttle can supply power on demand. Range and speed depend on the pedal-assist level, rider weight and terrain, so the listed distance is a best case figure. Disc brakes at both wheels provide braking, and the front fork absorbs small bumps.
