Upgrading your braking to a hydraulic system will take less than an hour and can be done for the cost of a new set of brake pads. All you need is a 5mm hex wrench. The brakes I installed can be found here. www.amazon.com....
Well it's about time. I flipped mine over when It came out of the box. Put Zoom Hydros on both ends. I had to wait 6 months 3 days to get my bike after paying for it. It's my favorite bike. Ride safe. It's always riding time in Houston.
Personally, I like the Magura MT5e brakes, the " e " designates for ebike because it has the motor cut out switch built in, I think it's up too series 7 now, but the MT5's are 4 piston calipers which gives you much nicer braking control, consider increasing the size of your rotors, you only have 160 mm, you can go up too 203mm for standard brakes and Magura makes a 220mm, larger rotor gives better braking control, brakes run cooler, long pad life but those cost about $120 each and you need to buy and extra adapter $20 each. Note: you still use the regular adapter for 203 mm but then you use the extra one in between the 203 adapter and the brake caliper, bolts are included, it's actually a very nice set up with the 220mm rotors. However MT5e's will set you back about $500, Shimano to my knowledge does not make a brake for ebike, there are different types of pads to consider as well, resin and semi metallic. Now if you want to stay with mechanical brakes.. heh you can get 255mm brake rotors from bicycle designer in USA and yes, they are HUGE but look awesome on a 26" wheel. If you change your rotors use a TORQUE wrench and make sure you use the correct pattern to tighten them, you always cross over diagonally to do a 6 point star, blue locktite if not already on bolts.... Zoom brakes are kinda the really budget brand like wally mart...
