Sturdy adjustable angle stem and long 350mm seat post improves fit for a wide range of rider sizes. The saddle drops down quite far without colliding with the rear rack, the high-step frame is lighter and stiffer than the step-thru, and it offers better weight distribution. An alloy chain guide protects your right pant leg while pedaling and reduces the chance of chain drops
High-resolution cadence sensor responds very quickly to pedal movement but the motor ramps up very smoothly, it doesn't feel jerky or unexpected. The bike is extremely quiet and the motor is known for being durable and offering some regeneration as you coast and brake, which saves brake pads and slightly extends range. New twist-throttle hardware looks good, still overrides any level of assist with full power, and is said to be less confusing and more reliable than before. Great fenders, kickstand, pedals, and suspension fork with lockout and preload adjust
Only available in one size and one color (consider the RadCity Step-Thru for two colors). The bottle cage bosses are positioned below the downtube, which isn't as easy to reach while riding. The gearless direct drive motor is heavier than the geared motors that Rad uses on their off-road models and doesn't freewheel as efficiently, it suffers from a bit of magnetic drag when pedaling unassisted or past the 20mph top speed
