DUOTTS
C29 Max
The upgrade is worthwhile for the design, brakes, lighting and battery, but the controller still limits how natural the bike feels.
City riding, commuting and long rides on surfaced roads, particularly for taller riders.
A more modern successor to the C29 with a larger battery, hydraulic brakes and a torque sensor, but unnaturally configured assistance levels.
Verdict: The upgrade is worthwhile for the design, brakes, lighting and battery, but the controller still limits how natural the bike feels.
Best for: City riding, commuting and long rides on surfaced roads, particularly for taller riders.

The best Duotts for power delivery, braking and high-speed stability, although the less expensive E29 is more agile and more comfortable over rough ground.
