Goals of the build:
Over-engineered, I will commute on this bike
Ability to maintain 35mph for extended periods
^^^^Edit - be faster than my bbshd 26er build. Id hit 32mph on flat. Bike weight 50lbs + my skinny ass at 130lbs
Inventory:
1 Enduro EBike frame with suspension (ready to go)
1 Cyclone 3kw motor (ready to go)
1 45a controller (arriving this week)
1 52v 30ah triangle battery (Em3ev smart bms 40a constant)
1 52v 20ah triangle battery (unit pack power chinese li-ion, I assume a 40a constant rating based on size)
1 alfine 8 hub 18t cog (at LBS being laced into 26" wtb asym rim with an 8mm dish pushing the hub toward the drive side)
1 dual freewheel chainring 44t/46t
2 magura mt5e brake sets
1 203mm rotor
2 scwhalbe big apples (love these tires)
a bafang black and white display
1 supernova m99 pro
1 26" sunringle mtx39 rim
I am getting a bit overwhelmed by this build at the moment, my end vision is parallel drive trains: human power and alfine on the right and cyclone belt drive on the left. Ive decided to build in phases instead.
Phase one will be straight forward using the common double freewheel and driving the alfine igh as its designed. In order to save components I am aiming for a 2k max output 52v x 40a. And dont tell me the alfine cant handle it, this little guy is unflappable: purchased as part of a specialized globe in 2003ish. In 2016 in converted that bike to a bbshd commuter that served about 4k miles till it was t-boned by a car in a crosswalk. I was moving at less than 10mph and was pretty much unscathed but the frame was ruined. I am not an aggressive rider and will most likely use about 1kw
Considering connecting my two batteries in a parallel config but will probably start with a toggle switch. Hoping a parallel connection would yield a 20a draw from each pack for a total of 40a at controller. But even if it shaves the amp demand off the 30ah pack i would be happy. Would a watt-meter attached to each pack provide accurate enough readings of v's and a's?
FUTURE PLANS:
Left side belt drive (sending the e-power directly to the wheel)
Cyclone tw has a bcd spider that attaches to the 6bolt rotor mount. I think i can pair this with an offset gates front chainring and perhaps some spacers to clear the rear caliper. but the part is $20 and they have $100flat shipping. considering returning my controller for the one on their site and picking up all the components through their site to make the purchase less painful. Also plan to see if someone makes the part state side.
WTB Ranger tires 2.8 x 26. Are there any 26inch tires between the 3-3.5 range?
Discreet turn signals and lighting
Torque sensing bottom bracket (id like the ability to switch between torque and speed sensing, maybe a relay?)
