Re: Help me develop the perfect throttle

Might work for riding on the street but I don't ever see a hand grip type throttle ever being useful for off-road. A thumb throttle works because it is out of the way and using a grip shifter with a half grip and detents does seem to work fine for me at least as it only will move when I want it to. ...

Re: Japanese Mid Drive

Did you see a price? And 3.5kg is in there as far as other systems go. If they went to a mag case like Brose did it would help shed some of that. 700w may be considered weak here on endless sphere, and I have been on here for years and know this. However I find for mtb use an efficient 700w system w...

There is probably a thread on here about the Nidec system but my search function isn't working.... http://www.imajteknik.net/uploads/nidec-ebike-system.pdf This came across my screen today and led me to the mtb version.

Re: TongSheng Chainwheel offset - dropped chain

I took the stock adapter, after cutting off the arms, and mated it to a Bafang style offset 42t, the smallest that will fit over the reduction gear housing, by drilling some new holes in the adapter to match the chainring. Is this BBS02 or BBSHD chainring? How big is offset in mm? BBS is 9mm and HD...

Re: Throttle use with trigger shifters?

I use a 10spd. grip shift on the right with a thumb throttle directly inboard of it. Works fine. Don't have a front der. but that would remain the same anyway.

Re: Lime Bike battery fire

This:

"In 2015, a Brooklyn man made a four-month, 2,700-mile trek from New York to California on a Citibike — and incurred a $1,200 late fee for exceeding the service’s 45-minute time limit on rentals."

I know it wasn't an ebike but epic all the same. Way to go buddy!

Re: 18% regeneration?

I was ruminating on today's ride about this thread and how it relates to how I use my regen on a daily basis. My decision to go with a momentary switch instead of variable, although as I mentioned the CA allows for changing v, to begin with was because it was the simplest solution. I placed it on th...

Re: 18% regeneration?

EPLUS has 9 regen levels - unmatched by any other bike edrive out there, DIY or factory. Now that's just retarded. Ever heard of variable regen, like thru a second throttle? CAIII displays allow for variable regen via the throttle if you feel like working two things at once or can be set to differe...

Re: More E-bikes found in NON-ebike media

So who's to say it wasn't a terrorist act with a match and some lighter fluid by some disgruntled BART rider/pedestrian type? Personally I think eBike shares are dumb and asking for problems like this and fail to see how they can ever make any profit, which after all is the point eh?

Re: Three pin plug type?

I emailed Justin first because their 72v 2170 battery looked to have the same type plug. He said that there are 4-5 different ones out competing to take over the pin plug market and theirs is a bit different. Thus here I am.

Three pin plug type?

This is the plug my 2170 battery uses for charging. I can't find out what type in a search. Need one to set up a charge cord for my Satiator and don't want to cut the one off the 4a stock charger....

Thanks in advance!

Since Tongsheng uses 110bcd spacing for its chainrings, you can use a Narrow/Wide (N/W) MTB chainring to prevent/decrease drops.
Not if the chainline is so whacked as it can be in stock form. That is why I use the offset ring, which is also narrow-wide btw.

Re: Rear Hub or Mid Drive for general XC riding?

I don't think a mid drive would work well with a single speed. Single speeding is all about staying on top of the gear as much as possible and either a torque sensing or especially cadence sensing PAS would just make it feel like mud. JMHO. On the other hand I am not that big a fan of rear hub motor...

Hi, hope this is the right area to post this. I am researching my first hub motor build. I want to put this on a bike with a Gates belt drive. Seems the easiest solution, then, is a front hub motor.

I thought they had scrubbed that video....Funny that my contact said they started using steel gears in February and that video was made in April. Bottom line is that they must have a steel gear now because Luna is going forward with the X1.
