Uno motorcycle reconfigures itself on the fly

This battery electric Uno may look like a regular motorbike at higher speeds, but when it slows down, the wheels realign themselves into a side-by-side configuration – seen in profile, it looks like a unicycle.

Gulak, a Canadian who is currently studying Mechanical Engineering at Harvard, is the brains behind the stand-up tracked off-road vehicle, the DTV Shredder. Unlike the Shredder, however, the Uno was inspired by a desire to save the environment.

In 2005, Gulak accompanied his father on a business trip to China. There, he saw the huge number of smoky, combustion-engined two-stroke scooters and motorcycles that were on the road. He wanted to create an electric alternative to those vehicles, but knew that it would have to be something pretty special in order to make a name for itself. He proceeded to build his first prototype out of angle iron, wheelchair motors, batteries and gyroscopes, and is now working on commercializing the vehicle through his Massachusetts-based company, BPG Motors.

“Because we’re such a visual society, I wanted something that was really going to stand out and show people that being green can be cool,” he told us. “When I was in China […] one of the things that seemed to be a problem was the congestion, so I thought if we could make a really small vehicle that could weave through traffic – it had to be the same power and abilities as the larger ones – that would make a lot of sense.”

“I wanted something that you could bring indoors, and charge in your apartment. Right now with electric scooters, one of the problems is that there’s nowhere to charge them, and they get vandalized on the road.”

Not unlike a Segway, the Uno uses gyroscopes to maintain balance at lower speeds – a rear kickstand supports the vehicle when it’s parked. At higher speeds, as it’s moving, the wheels realign themselves into a more traditional, one-behind-the-other motorcycle configuration. This is to provide stability, and to make the handling less twitchy. The version that Gulak is now working on, however, has three wheels. When it hits 15mph (24km/h), the middle wheel moves to the front, while the outer two move to the back and squeeze together.
