Preventing Seatpost slippage
Zinn Cycles has the first production 32er full suspension bike for big and tall riders
We just finished up this new e-bike for a local Boulder woman who is about 5 feet tall. As usual, she could not find a bike that fit that was not a 60 pound hybrid clunker. She has been cycling for ages, and wanted an ebike that felt like a regular bike, not her grandmothers tricycle. So she found us and we started the process to build her dream e-bike.
