High stability
Intuitive and good-natured handling
Light integration
MyO customisation
Comfort imbalance between front and rear
Sometimes unnatural power output of motor due to its lack of a torque sensor

A great ride and visual control of the motor’s support level from the bars
Well specced
Head unit to control and monitor motor
Battery easy to deplete quickly
No mudguard mounts

Hugely fun, even with the motor switched off. The Gain is a real pleasure to ride
Subtle assistance, can be bespoke
Wheel upgrade is a must to get the best from the bike
