bikedrive electric bike kitMaxon’s BIKEDRIVE is a permanent-magnet ironless-core electric bike motor that outperforms virtually everybody in terms of power density, acceleration, heat dissipation and overall efficiency. BIKEDRIVE blasts out of the gates with 500 watts continuous while operating at an unheard of 85% efficiency (75% on steep hills). That’s over three times the efficiency of most electric bike motors. Over-heating BIKEDRIVE is impossible.

Most e-bikes don’t have the weight distribution necessary for serious riding because of excess weight and poor efficiency (over-heating).
