Written by Hi, After working with the powerful and efficient BLDC motors now I am starting to think about using them as an engine for my bike. I live somewhere uphill where I have to pedal about 1 KM on a 15 Degree steep road to get back home. This is the sole reason behind me not taking my bike out often. Back to the point, a BLDC is a powerful, light and efficient motor which can be used for this purpose. There are many bikes out there on the net which has been converted to Ebikes with the aid of BLDCs. There are two main ways of converting a normal bike to a motor-powered-bike: 1- Using a hub motor A hub motor is an integrated motor that is placed inside a hub making it easy to be installed on your bike. A hub motor can come with a rim or it can be installed in your bike’s rim. iejiovf 1 – Crystalyte starts at $299 (900w)/$369 (900w)/$699 (> 1KW) motor only : http://www.electricrider.com/crystalyte/images/x-408sf-26.jpg http://www.crystalyte.com/index.html and http://www.electricrider.com/crystalyte/sparrow.htm 2- By adding an extra motor An extra motor (AC or Brushed/Brushless DC) can be installed on a bike which requires mechanical work. No modification needed : 1- With drive ring One example that uses a drive ring that can be installed on spikes of your rim and provides you the possibility of attachments of a motor with a timing belt: http://www.bikeengines.com/KitShotTanaka40.gif http://www.bikeengines.com/index.htm refere here for sample builds : http://www.bikeengines.com/custtest.htm Modification needed: 1- http://www.cyclone-tw.com/0bike.htm http://www.youtube.com/user/luc59457 Nice sources http://www.bik-e.com/ Lists motored bikes http://www.youtube.com/watch?v=lmkLrDk9zEc a sample project using a normal BLDC http://www.evalbum.com/ for an album of Electric Vehicles
