Custom E-Cruiser has features for disabled rider

e-crusier

As [AussieJester] noted in the first page of his build log, most people’s idea of a “custom-made” electric bicycle involves strapping some electronics and a hub motor onto any off-the-shelf bike. He needed a bigger challenge, so he fabricated his own frame to build a stylish electric cruiser. This bike has a 2-speed transmission and a massive Turnigy 80-100 brushless outrunner motor, which pushes out a top speed of 45mph.

You may have noticed what look like training wheels in the picture above, and you’d be half-correct. [AussieJester] is a paraplegic, and needed to guarantee some stability both when transferring from his wheelchair and when coming to a stop. The best feature of this bike, however, is that these small wheels are retractable. A linear actuator lowers them for slower speeds and for mounting/dismounting, but picks them back off the ground once you are up to speed, maintaining a true 2-wheeled experience.

Stick around for a couple of videos after the break: a first-person POV showing just how quick this bike can move, and a demonstration of the actuators. Then check out another EV pioneer in the world of skateboarding.

30 Mph electric mountain bike

A 48 volt power house pushes this mountain bike at speeds up to 30Mph.  That’s a bit of a boost from many off the shelf E-bikes. [Jennifer Holt] wanted speed, and to retain the off road capabilities of her bike, so she made a custom one. As you can see in the video, this thing gets going fast and hills are no problem. She says that it will toss you off if you slam the throttle, and we believe her. We know some of you will insist on chiding her because she’s not wearing a helmet in those videos. She did manage to break her elbow offroading in the video after the break. That part is edited out though.
