If you're looking for an even more intense workout on your morning bike ride to the office, you need to look no further than the Raxibo, which packs an extra set of pedals on the handlebars that exercise your arms and upper body as well.
By incorporating all of your limbs into a ride, the Roxibo promises a more full body workout. And since the handlebar pedals are connected to the bike's drive train, in theory it should also provide more power when climbing steep terrain. Although, at the cost of a little added weight to your ride thanks to all of the added mechanisms and gearing.
So you might not see much improvement when it comes to speed if you were hoping it would shave a minute or two off your commute. The bikes start at around $US2600, but can be configured and upgraded with larger wheels for a few hundred dollars more. [Roxibo via Gizmag]
