Custom Aluminum Enclosure for Fast Ebike Builds

This slim enclosure fits the 20ah batteries for NB Power Motor 3000 watt kits.

Moto Electric Racing's metal shop makes these enclosures in the USA. You can order them in the color you want and ready-made for the NB Motor kit or blank (you drill your own holes to install the kit of your choice.)  This is the hands down the best way to secure a controller and battery inside the frame. It could also be used to carry cargo. The cover lid attaches with bolts into tapped holes and has a mesh backing to allow the battery and controller to cool.

Customize your enclosure! Custom colors available! Send a message to support@custom-ebike.com to indicate your color preference. The shop will approximate the color as best as it can. If you dont want the pre-cut holes, we can eliminate them! Send an email and note your order!

Two versions:

20ah size is approx. 3.5 inches wide inside to inside

If it is in stock, we ship right away. Otherwise, allow 3-4 weeks for build and shipping. NO RETURNS.

Note that the enclosures are also offered as part of a package and you can save money on the motor, battery, and enclosure and order directly from Moto Electric Racing
