Bamboost E-Bikes by HERObike
Last year at the North American Handmade Bike Show, we saw bikes from an Alabama based company, HERObike. This company takes a different approach at the components used to make the bikes. This year the company will be showcasing its upcoming Bamboost e-bike, which features a composite frame associated with adds balsa wood and 3D-printed parts.
The main components of the Bamboost consist of an inside layer of carbon fiber iPhone case, followed by laminated layers of woven bamboo, an actual balsa core, another layer coming from all woven bamboo, and finally a layer of resin. Area that need to be rough and tough since they are subject to abrasion, such as the rear tire drop-outs, are protected by one more layer of carbon fiber. To further strengthen the drop-outs, metal inserts are also used.
The sides as well as the rest of the bike are joined together using a series of 3D-printed spacers. Together those side panels/spacers form the frame. These are not simply joined onto an existing aluminium frame. To add functionality to the Bamboost, a hand-made leather cargo bag sits inside the frame while the bike is in use, and can be removed and carried by the rider when the bike is parked.
The design is courtesy of Lance Rake of HERObike. The mechanical and gratification specifications of the bike are still being ironed out, the bike will utilize a SRAM E-matic rear hub motor and rack-mounted battery. The Bamboost will be priced somewhere around US $2,500 and 3,000.
