| I approve of this approach of taking a good bicycle and adding minimal e-assist. But I'd keep a 7 speed rear derailleur. And I'd probably prefer a rear geared hub to a front one. We really need 36v-15AHr or 48v-10AHr and those bottle batteries don't quite manage this. Perhaps that could be packaged to fit in the bottom of the main frame triangle. Obviously these guys are limiting power but the minimal geared hubs can be over-driven to about 750W. So 48v and 10-15A is both do-able and suitably peppy. Powered 25mph should be ok.  Electric Bikes originally shared this post: Electric Fixie This is the lightest electric bicycle available in Australia. Whilst most electric bicycles weigh in excess of 27kg, this model weighs only 17.5kg, it is a slick and stylish electric bicycle that we've designed completely to be exceedingly simple, practical and robust. It is designed in Australia, uses the Panasonic tube battery and is well suited to the mini-motor or any larger power motors. It comes with a medium/large sized frame only, suitable for riders between ~ 170cm - 190cm. The fixed gear bicycle typically has a single fixed gear, no brakes and a racing frame and component design optimised for speed and efficiency. The electric fixie takes these concepts and has urbanised some features; such as brakes and free wheel ability (flip-flop rear wheel) to create a high performance bicycle that is designed to be the perfect urban commuting vehicle. The deficits of a single gear are completely taken care of by the slick bicycle design and electric motor. Using a custom designed reinforced frame, an advanced light weight 9Ah Panasonic lithium ion battery shaped into a water bottle and a front hub motor, this is an exceptional bicycle. The bicycle is street legal with the 200W motor and has a range of approximately 40km and speed of 28km/hr with light pedalling. Upgrading to any of the larger 350 - 500W motors provides a higher top speed (30-35km/hr). The fixie electric conversion kit and fixie bicycle can be purchased online but you'll be required to assemble the components - very easy. The bike costs $600, the conversion kit $1050 and delivery Australia wide $45. The bicycle comes with a spare set of retro style handlebars for comfortable and stylish riding and also a small tool box with all items needed for its assembly, which takes only about 15 minutes. It's an awesome limited edition bicycle (only 50 ever made) that can be ridden either electric or non-electric. Approximate ranges and speeds of the electric fixie with light pedalling and different motor powers are: 200W: 40 km range, 28km/hr top speed 350W: 25 km range, 32 km/hr top speed 500W: 20 km range, 35 km/hr top speed  [from: Google+ Posts] |
