A couple of weeks ago I went for a test ride on a full carbon MTB eBike from Furo Systems.
The Sierra is a carbon full size mtb. Its’s a great looking bike in the flesh and uses a special type of motor (a Bofeili motor) which sits in the crank but is hidden. It it sensitive to pressure so it increases the power the more pressure you put on the pedal.
Firstly, it is pretty keenly priced for a full size hidden battery eBike, let alone with a carbon frame.
Secondly, the motor is almost invisible so it looks like you are fully pedal powered. This bike also has the battery hidden inside the carbon frame so it does look very like a chunky MTB.
