Fatty vs Scrappy Doo, take your pick

Recommended Posts

 Both bikes have a 750w big magnet Bafang. The fatty's 750 is inside the stock 350 motor housing. Fatty has a 48v 30ah battery driving a 35 amp big momma 18 fet controller. 

 

The Fold started life as a Foldx7. I replaced the stock 20 x 80mm rims with more sporting 24" x 65mm  rims laced to a 750 Lindsey motor, which slightly increases overall gearing over a stock Fold. That still leaves the overall gearing a lot less than the fatty so it's able to make due nicely with just a 25 amp controller,  

 Both bike's lighting is powered off of the main battery.

      I am unable to turn the battery key that came with my Sondor's. See the linked video. Would welcome advice on what might be wrong and/or how to remedy the situation.

      After upgrading the front crankset, rear freewheel, (53/17 final gear ratio), chain,  LT48 battery, 20-amp controller and display the bike was a beast. Easily commuting to work at 26-27mph and hitting 28-29+ with a bit more effort. The issue was at those speeds in LA traffic I needed the ability to stop fast too. And re-adjusting my brakes every ~2-3 weeks was also getting annoying. The solution was new tires, hydraulic brakes, and Rotors. Here's what I got:
      --
      Rotors: Shimano Deore RT66 180mm 6-Bolt Disc Rotor
      Brakes: PASION E BIKE MTB Hydraulic Disc Cut Off Power Brake E-Bike (This is basically just a Shimano Hydraulic brake set that's been modified to have the motor cut-off. Make sure to select the right option, in my case it was the second one from the left as my controller has the 2-pin (red) motor cut-off).
      Rotor Spacer: Shimano F180P/P2 Disc brake adapter
      Hose Wire Clip Clamps: Jiyaru Bicycle Cable Guide Brake Line Holder Hose Wire Clips Clamps (To route the hydraulic hose by attaching these to the existing closed cable lines).
      Tires: Schwalbe Marathon Plus HS 348 Road Bike Tire
      --
      This thing stops like a beast now and with the extra traction from these tires this is a nice safety upgrade. Should reduce the changes of flats too as these tires have built-in tire-liners essentially. So far really happy with the upgrade. :)
      I hope this helps somebody out!

      You may have seen some ads here for the product "Booster Battery" for the SONDORS eBikes. 
      We highly warn against these batteries they are really dangerous. Connecting two different batteries together may/will cause the weaker battery to drain first to the point where voltage becomes zero, at this point the battery will be damaged forever with no way to repair it. That may be fine for some of you but, here comes the dangerous part. The larger battery will continue to draw from the weaker battery which have already been exhausted and it will get extremly hot - a extremly hot and exhausted battery will explode and burst into flames. You are getting yourself and other lives in danger when you're connecting two batteries that are not the same voltage and amp hour. You might have been doing this with no negative effect yet but obviously you have not done long term testing. If it was this simple, someone would have done this along time ago.
      Lithium batteries in general are extremly explosive and highly flammable especially when you are not utilizing it properly. Here's a video of what happens when lithium batteries get hot:
