fit

Hedgehog best fit for riders with an inseam of 17" to 21". First time riders feel safest with their bottom on the saddle and their feet flat on the ground. That's how a child with an 18" inseam will fit the Hedgehog with the seat post dropped as low as possible. Once kids get more comfortable on two wheels, they'll want to sit on the saddle with the balls of their feet on the ground. Thus, a confident rider with a 17" inseam and a first-time rider with a 19" inseam will each ride with about the same seat height.

“What is truly amazing is the attention Open paid to making it work exceptionally well in every configuration. The U.P. doesn’t just accept different [wheel/tire] standards - each feels native.

Peloton Magazine

“The Open U.P. will change where you ride. A long-term review of this gravel/’cross/road bike proves that it really is as versatile as it promises. It feels natural on pavement and somehow still takes to the dirt like it was designed for it—a blend I’ve yet to experience with other bikes.”

Bicycling Magazine

“I really shouldn’t start my review with this, but I’m going to. The Open UPPER has become my all-time favorite bike. Period. End of story. If you buy one, you’ll love it.”
