Giant Trance3 BMC 600 build
Well figured before and after should be done before I had trashed the thing.
Before it was one of these.
Now as an e-bike it looks like this
That is after
Building a couple of wheels with 12ga spokes
Upgrading to 8inch brake rotors
Installing a 600BMC rear motor with a crummy axle
Replacing the MTB crank with a 53-tooth road crank and finding an 11-34 freewheel
Modding a throttle for remote operation
Building my first real A123 pack 2p14s
Installing a rear rack and pack
Fitting fenders that didn't fit.
Putting together a brake motor cutout switch
Modding a Kickstand so it would fit
Putting on a torque arm. and a few goodies lights, speedo mirror ect.
Top speed 1st gear locks on at 17mph 2nd gear at 30mph controlled by thumb on the the Shimano rapid-shift front derailleur. Finger lever used to release the locked throttle.
Climbs hills 4mph faster than my GM 500w motor at the same 48V but it is not silent. Cushy ride across the playground, down the dirt roads, off curbs ect.
52lbs with the cable lock, kickstand , 4.6AH bat that gets me near 7 miles at 30MPH. Does not tear my back up like the hard tail Schwinn did.
Still working on;
Battery pack 2
600LM bike light kit
5 amp and 8amp chargers as well as 2.8 amp on board.
single wheeled trailer for extra batts and range as well as hauling
lets not forget to replace the hose clamp being used for the torque bar
This build took just over a year and it was done with little use of my damaged right arm. The arm is good enough to ride now so I am doing plenty of it 190 miles so far.
