A big breakdown of the electric bike build I just completed. This is a 27.5 mid fat Iron Horse Compadre bike that I installed the Golden Motor Edge 500 watt electric motor kit on, with a 48v 14.5ah battery. Totally happy with the results.
Cost breakdown:
$390 - battery
$180 - bike
$450 - golden motor
$150 - shifters, grips, other stuff
Most decent ebikes will run you $1500 new, and that's about right given it does take time and effort to put one together yourself. I think radpowerbikes has a good thing going with their bike. I could upgrade my shifters and brakes and have a more solid bike. This is sort of a test bed to see if I really want to move this kit over to a more expensive bike, but for now, this setup is working well and the technology in this bike is old school and should hold up if I do the right maintenance. It feels solid, and I have several 15+ mile trips on it with zero issues.
I added a few accessories to the kit like a luna charger that allows me to charge at 80,90 or 100%. I just recharge to 80% since my battery is oversized, it should last longer if I never push it to 100% charge. I also got a heavy kryptonite lock for it and a bag with the basic tools, lights and flat repair stuff in it. Given I am biking much further than normal, I really need some tool to fix issues if I am so many miles from home.
So, my main use is to bike down a river trail 5 miles to get to the beach. I just want to transit to that location. From there I can pedal around normally, then battery power back. I used to bike that route and just don't like how worn out I was on arrival. Its flat and easy biking, so a cheaper bike should hold up with the right maintenance. Faster than expected, better power off the line than I thought it would have. Really happy with the build and its a lot of fun.
Also, the bike has a programmable controller, so you can plug in USB to it and dial in some key settings. One is the amount of regen braking, which is critical because you want to really set your amount and you can crank it so much that you never would need normal brakes, but the brakes are on or off. It would be really neat if they had variable braking, so you could really use just the motor and control the braking from a little to a lot. You get just 1 amount, and I dialed that in to about a middle setting. If I am braking gently, I just use the front brake, the rear kicks in a lot of force through the motor. The other thing to really dial in is the throttle response. I thought, well, 100% right. You get a violent bang from the motor when its set to 100%, even if you just turn the throttle a tiny tiny bit, its like the first notch is too much. So, I backed it down to about 65% so that the throttle rolls in. That makes it nice. That's really my only complaint is that the throttle is a bit odd, but you can dial it in with the controller, I just wish the throttle had more fluid control over the torque. With it backed off to 65%, it puts a delay curve to your inputs, so that adds a bit of delay. I just wish the throttle was smooth through the band, but that is a compromise you get. You still get 100% power, but you get the full power slower, which you really need because its weird at 100%. They probably could do that a little better. I never would have thought I needed to delay my throttle inputs.
