Our take on the 28" Step-Through Electric Bike for Adults

The CrazyBird R3 is a 28-inch step-through electric bike built around a 52V system with a torque sensor, so pedal assist responds to how hard you push rather than just how fast you spin. The low-step frame gives an upright, relaxed riding position, and it comes with fenders, a heavy-duty rear rack and hydraulic disc brakes. It uses named components — Bafang, Shimano, Kenda and Selle Royal — and ships 95% assembled. It suits riders who want easy mounting, hill capability and cargo capacity more than a sporty, aggressive ride.

Questions and answers

What makes the torque sensor different from a cadence sensor?
A torque sensor measures how hard you pedal, so the motor adds power in proportion to your effort. Cadence sensors mostly react to pedaling motion, which can feel less natural on hills and at low speed.
Is this bike good for hills?
The 52V system is the main reason it holds up on climbs, and the torque sensor keeps the assist smooth as you push harder. Steep grades will still depend on your own pedaling effort.
How much assembly is required?
It arrives 95% assembled. You install the pedals and adjust the handlebars, then check the brakes and tire pressure before riding.
What comes in the box?
The bike with its 52V battery, integrated fenders, rear rack and the named Bafang, Shimano, Kenda and Selle Royal components. Small tools for the pedal and handlebar setup are typically included.
Who is the step-through frame for?
Riders who want easy mounting and a more upright, relaxed posture, including commuters and older riders. It is less suited to riders wanting an aggressive, forward-leaning position.
