Corsa E Bike
I decided to build an ebike, I found a 2010 Corsa than had just a few miles on it. I ordered a Bafang 750Watt BBS02 with a DPC-18 display and a 48 volt Jumbo Whale Shark battery all from EBike-Essentials. I used a California E Bike motor bracket and T Cycle Fully Configurable battery mount with a Bacchetta frame clamp. I had to extend the battery cable,speed censor wire and the throttle wire. I'm using Velocity 650 wheels and Terry 650x28 steel bead tires (don't to have tire trouble at high speed) I bought an adapter form amazon and I installed a FSA 53 chain ring on the Bafang motor. The battery lasted just a few miles and quit working. I could not find anyone that would ship the battery and I don't think E Bike Essentials would even replace the battery without a warranty. The battery had seven bad cells so I rebuilt the battery using the good cells I built a 13x6 cell battery. I reprogrammed the controller,with 0-9 power settings. Setting one has 8% power (14 amps total) or 11.2 amps,setting 2 has 20%,3- 30%,4-40% all the way to 100%.. I was really unsure about the bike because of all the weight ,motor weighs 9+ pounds and the battery 10+ pounds but other than being a little heavy to load on the bike rack I never noticed the extra weight while riding. In the past I had to stay in the draft when ridding at any speed over 20MPH, but with this set up I ride in the back at a safe distance and really really enjoy the rides. In setting 1 (8%) power I can ride with the group on flat ground 20 to 21 MPH. With the faster group I ride in setting number 2 riding 21MPH and up. If their is a incline I have to raise the power because it a heavy bike and doesn't like to climb without power. I charge my battery to 80% so when I start a ride the display says I have about 88% of power remaining. I have never had the power setting at 100% I can't spin the crank over about 40MPH. Testing the rebuilt battery I was using about 80%power and averaged 35MPH for 3miles.. In Florida we don't have many hills where I live but the ones we have I can climb at speed over 37 MPH. When the battery quit I was about 20miles from my car and rode back without power no problem just had to ride at speed of 16 or 17. Rode yesterday 44 miles average speed of 18MPH and with 450 feet of climbing. Top speed of 30 MPH, Rode the 44 miles in level 2 when I returned to the car I had 48% of battery left. I plan on riding tomorrow to run the battery to its shuts off. Didn't charge it up after the 44 mile ride yesterday. I need to know where the shut off point is on the display. I really didn't know what to expect before I built the bike but at my age (72) I can ride with the fast group keeping a safe distance in the back and not having to keep my heart rate close to max all the time.. If I had it to do over I would not have purchased a battery from E bike Essentials, and I would have change the wheels to disc brake and 26inch that way I could use a big 1.5inch tire for a smoother ride.
