http://www.gizmag.com There’s a few reasons why cycling has remained a popular form of transport for over a century. It’s cheap, keeps you fit, is environmentally friendly and it’s fun - usually. Unfortunately it can get a little less fun when you hit a steep hill or have neglected your fitness for a while. This is where electric assist devices such as the Gruber Assist can come in handy. It still lets you do most of the work, but helps to make the job that little bit easier. Whereas electric bikes such as the E+, the eneloop and the Gocycle require the purchase of a complete bike to get some electric assistance, the Gruber Assist can be retrofitted to practically any bicycle provided it has a seat tube with an inner diameter of 31.6mm.en gizmag.com http://www.gizmag.com/gruber-assist-electrifies-just-about-any-bicycle/11609/#comment-33247 http://www.gizmag.com/gruber-assist-electrifies-just-about-any-bicycle/11609/#comment-33247 Tue, 21 Sep 2010 22:29:37 -0500 http://www.gizmag.com/gruber-assist-electrifies-just-about-any-bicycle/11609/#comment-2383 http://www.gizmag.com/gruber-assist-electrifies-just-about-any-bicycle/11609/#comment-2383 Mon, 18 May 2009 15:34:27 -0500 http://www.gizmag.com/gruber-assist-electrifies-just-about-any-bicycle/11609/#comment-2302 http://www.gizmag.com/gruber-assist-electrifies-just-about-any-bicycle/11609/#comment-2302 Mon, 11 May 2009 09:55:38 -0500
