![]() With the BBS factory set to 41V LVC and adjustable to a max 43V, do you ever hit this voltage? Also do you know what the BMS LVC is set to on a 14S 18650 pack? I have a hub motor in my other bike and it gets slammed pretty hard when the wheel drops.Ĭurious about the 14S9P 18650 battery set-up. The thing that is currently discouraging me from the Nuvinci is the weight of the thing and the shifter design. With hills the issue isn't how the pads get compressed but more how your rotors and pads deal with the heat.īigger better rotors are the best solution for that. (You may find them on eBay sometimes too.) There are some commercial options as well, but seem to be OEM-only, eg. I like the simplicity of being able to adjust my brakes on the road with just a simple multi-tool. Hydraulics are great, but if you ever have to open one up it can be a mess and a bleed kit is necessary. There's lots of ways of getting hydraulic brakes to work, most require building a switch into the brake pull which addsĬomplexity and something else to fail/maintain. I don't do a whole lot of dropping the rear wheel off cliffs these days. Haven't got a Nuvinci on order yet but think I'll want it. #Supertux paint plusMost of the time I ride it standing on the pedals.Įbikesvi wrote:Thanks for the specs, I've got a lower end Motobecane Fantom and waiting for a BSS02 to arrive for my first bike build.ĭid you consider any means of using the hydraulic brakes? I guess BB7 200s will do but I've got a couple 15 degree plus hills to negotiate and hope to try the hydraulics. ![]() I am debating putting another suspension seatpost (Thudbuster / Thudbuster ST) on this bike. I put a comfort seat that is split down the middle and bends to my butt shape on it. O Easy to saw off a chunk of the right hand grip to make room for half twist throttles. O Side horns let you change grip to avoid cramps. O Ergonometric grip supports you palms for long rides, no carpal issues. (Did You Know? Front forks have a maximum disc diameter rating.) ![]() O Pair with 200mm rotor on the rear and 180mm rotor on the front for maximum stoppage & heat dissipation. O Won't interfere with most hub motor covers. O The best mechanical brakes money can buy and field serviceable. O I have added these to four bikes, my two ebikes, gfs' eMotion ebike and her normal bike and have yet to get a flat on any of them. O Requires a special tool to remove or loosen the bolts. O In addition to giving more security, they are unlikely to loosen like a standard skewer with a lever might. Pinhead Locking Skewers on the front, seat and rear tires: Mirrycle Incredibell Original Bicycle Bell ($9):Īlthough not strictly electric in nature, I added my standard anti theft / anti flat / no fail braking / comfort system to this bike as well.

I suspect the Bafang BBS02 is labeled at "750W" for legal reasons, but it is capable of so much more: (Theoretically: 58v 25A = 1450 W)Įven with all my shenanigans riding up grass hills and whatever else 'off road' I could find on the way to work, Top record speed has beenģ1mph which is the limit built into the controller/display (50kph). I drove this straight up a very steep hill in granny gear #3, no pedal, the motor and gears strained, but no problems. The sprocket I have is a 10 speed SRAM (PG-1070 I think) in the range of 11-36T with a KMC 10 speed chain with a 'MissingLink' connector. Now my controls are the same for both ebikes. ![]() I chopped the funky Bafang connector off it and spliced it into the half twist from ebikes.ca. I pulled apart the BBS02 thumb throttle and it's a hall sensor type. ![]() I replaced the Bafang BBS02 thumb throttle with a half-twist throttle so as not to interfere with my shifters. I had to remove some nice hydraulic brakes in favor of the cheap Chinese cable pull handles, but replaced those with BB7's and bigger discs so it's all good. =6&t=51147Īfter a few thousand miles on my commuter bike, I brushed the dust off this 29er and made it an awesome "dirt" bike. I rode it hundreds of miles while waiting for parts for my first ebike and discovered it was not the optimal platform for a commuter ebike.Įventually I bought another bike for that and that build is detailed here. Knowing nothing about bikes, I bought this Motobecane 29er two years ago (2012) to be the basis of my first e-bike. ![]()
