10 kW Electric bicycle pusher project
Over christmas I gathered a few bits that I had knocking around and came up with this bicycle pusher. Originally I was going to make an electric scooter, but I didn't have anything lying around to make the front end so instead I thought I would attach it to my mountain bike! Power comes from a pair of 4000mAh 5S 40C (37V) Zippy batteries through a 200A ESC driving a Turnigy 80-85 170KV outrunner. There is a centrifugal clutch that transmits the power via a chain to the pusher wheel. These initial tests are promising and there is sufficient power to accelerate my 280lb frame from a standstill. As it is a bit icy outside my nerve gave way at 20mph, but there is way more to come! I need to figure out how to get more traction though as at the moment there is more than enough power to spin the pusher wheel! This wont be a problem if I can get the system working with a scooter as my weight will provide more than enough pressure on the rear wheel. Here is a link to the motor http://www.hobbyking.com/hobbyking/store/__14426__Turnigy_CA80_80_Brushless _Outrunner_50_80cc_Eq_.html
