More Photos of Building my Electrified MTV LeRun Skatebike

In the My DI-WHY Electrified MTV LeRun Skatebike we were introduced to an eLeRun. The builder is Braxton M. from Michigan. He filled me in on braking.

There is some braking due to the motors natural resistance but overall it’s more like a skateboard than a bike. The speed is a max of about 13mph (my max comfortable speed anyway lol) so a quick step off is easy enough to do if needed but you get used to the natural motor braking with time. The bottom bracket is still in place, there is two polycarbonate 3D printed pegs pressed on. Eventually I’m going to replace the old brushed motor for a brushless one for a bit more speed and efficiency. In addition, stronger regen braking will be added with a different motor controller and I may add a manual brake at some point. Battery pack is custom built with around 30 miles of range per charge and there is an integrated 12v converter to run the lights on the sides of the battery case.

Braxton included some interesting images from the build.

I am impressed.

My DI-WHY Electrified MTV LeRun Skatebike

Here is something interesting. wer2000 on Reddit electrified an MTV LeRun. As the bottom bracket, cranks and pedals were replaced with stationary pegs, there are no brakes. One solution could be to add a brake like Minson uses with a brake handle under the seat. The speed control is mounted on the seat handle.

In his words

I had a geared 350-watt motor laying around and a 500 watt-hour battery used on a different project and decided to have some fun with them since they were just sitting around. It started out as more of a joke but its honestly quite fun to ride. It rides relatively stable and the max speed (~13 mph) is more than enough given the circumstances. As far as I know, no one else has done something like this so I guess I can at least say that I’ve done something unique?

How do you control the speed?

Leaning for turning and I’ve got a little vertical thumb throttle cleverly attached to the little hand grip in the front of the bike.

Motor mount is the only frame addition. Motor and controller were just laying around and the battery is from a different ebike I built awhile ago.

Most of it is in part to 3D printed parts. Exterior of the battery module is printed and even the foot pegs (with a super high density that is). The black coat also helps in cleaning up the welding motor mount though as my welding is certainly not top tier.
