Just as promised, we're proud to announce the upcoming arrival of our first ever ZB-EKITs ! Our ETA for these new kits is June 15th !

The 500W ZB-EKIT electric bicycle engine kit is the performance champion among all other electric bicycle engine kits. By using your bike's gearing, it can climb steep hills, accelerate faster and achieve higher cruising. The 500 watt motor will drive 20" folding bikes up to 21 mph and 26" bikes at 27+ mph on level ground. At cruising speeds, the motor will draw about 15-20 amps, and when accelerating and climbing it can draw up to 35 amps. The 500 watt motor performs best when coupled with a high performance 24v 24Ahr battery. With this battery, you're able to achieve up to 45 miles on level ground at average speeds of 15-18mph. Higher speeds and/or hilly terrain will reduce the range from 20% to 50%.

In order to achieve maximum performance from our 500 watt motor, you must use a battery that is capable of supplying sufficient current. Using batteries that are too small will give poor climbing, slow top speeds, shorter range and may damage the motor controller.

The kit is easily mounted on most diamond frame bikes with the supplied mounting hardware. The kit is supplied with all parts listed below - batteries must be ordered separately.
