CMACEWHEEL RX20-MAX – 1500W – A foldable electric bike with two motors that surprised the whole of Kruunuvuorenranta!
First meeting in Kruunuvuorenranta
When the CMACEWHEEL RX20-MAX arrived at the test drive point shared by electric bike manufacturers in Kruunuvuorenranta, Helsinki, the atmosphere was electric. The test team opened the box, and in front of them stood a sturdy folding electric fat bike – massive fat tires, a sturdy frame and the promise of a dual motor. In an instant, we knew that this bike was no ordinary ride.
Feels at home in city driving
The first kilometers were driven on smooth asphalt. The 2 × 750 watt motors came to life and provided powerful but controlled acceleration. The RX20-MAX traveled the city streets agilely, steered precisely and stopped with pinpoint accuracy using the powerful disc brakes. The folding frame made it easy to transport – the bike slipped into the subway, bus or car trunk without any problems.
The hills become a playground
The steep hills of Kruunuvuorenranta were the perfect test. The RX20-MAX climbed them effortlessly with the power of the dual motors. Every climb felt easy, and the rider could focus on the scenery and not the heaviness of pedaling. This bike is not afraid of hills.
In the field in its own area
When the road turned to gravel and the terrain beckoned, the RX20-MAX showed its true strength. The wide 20×4-inch tires bit into the ground and held their grip on sand, gravel, and roots. The front and rear suspension softened the ride for a smooth ride, and the rider could enjoy every trail without compromise.
Structural strength and practicality
The aluminum frame is durable, but the folding mechanism makes the RX20-MAX easy to transport and store. The bike weighs about 30-33 kilograms, but it can carry up to 150 kilograms. The recommended rider height is 170-200 cm, so it is suitable for a wide range of riders.

Manufacturer's warranty – you deal directly with the factory that sold the bike
