The 4StrikeBike concept would see riders pedaling with both their legs and arms, for a more complete workout and greater power
A freewheel mechanism allows both drivetrains to be used simultaneously, or either one to be used on its own
Both of the hand pedals can be locked into their highest position, allowing for a more stable stance while riding using leg power alone
An integrated “steering stabilizing mechanism” helps keep the hand-pedaling movement from sending the bike off the road
A belt drive runs from the 4StrikeBike’s handlebars down to the bottom bracket
The handlebars are reportedly able to turn from side to side without interfering with the belt drive
Although cycling is a great form of cardiovascular and lower-body exercise, it doesn’t do a whole lot for the upper body. Over the years, various arm-and-leg-powered bikes have been developed, such as the Raxibo. Now, however, retired surgeon Lex van Stekelenburg is hoping to get his own such vehicle into production, in the form of the 4StrikeBike.
