If that freewheel is like a couple I just opened recently then removing much material is not an option. The interior is stepped like the exterior so it has a thin wall for it's entire length. If what you are trying to do is make it small enough to fit the 11t further in the freewheel body it's not g...

What about the Stator? It needs to be fixed in the middle of the axle, will it have threads and bolts holding it in place?

Gary

IMHO I think all current systems are a compromise. None of them do best in all of your categories.

What I would really like to see is a hub motor that can do like 2kw continuous and has a built in transmission of some kind to get multiple gears.

get the plate, look up address , go at night , slash tire, just one every time.,........ :mrgreen: :mrgreen: I do step one and two, then drive by the house a few times until the truck owner sees me and knows I know where he lives...

Unless you are doing a lot of big hills or a LOT of stop and go or are building a very high powered rig, I would just forget about regen. It really isn't that useful for what you get back in energy vs. the added complexity. It is effective as a break IF you are regularly riding in conditions that m...

I would say you are correct about the components so far. If the black wire and the red with white trace go to opposite ends of the battery bank (the batteries should be in series) then that would be where you plug in a 48 volt lead acid charger. One note: The battery is 12 volt 20 amp hours , not am...

Couple of questions. Did you install that brake switch T in the front brake line? If so did you change the front brakes from your Hayes to the Maguras? Reason I ask is because those switches are not compatible with Dot 3 or 4 fluid. It will cause them to stick. The details are in this thread: Regen ...

The main advantage of the CST motor, with the cassette, over the BPM motor (the same motor but with a freewheel thread), is that the cassette allows a wider gear range. The tallest gear on a freewheel is 12T, and then only on one type that may not be the best in terms of quality. Most normal freewh...

front wheel you mean?

Q100 is a geared motor with internal clutch so as soon as you let off the throttle you will lose hall sensor signals.

Last time I got asked that question I tried a new answer. I just said yes it would work but it's like pedaling an exercise bike that's on steroids. They then understood it takes a lot of work...

Here's a log I kept for a while before I got bored. I was shooting for 20mph average speed to stretch my limited battery power all the way home. Might be some useful info in there for ya.
Gary

I AM A NEWBIE,but would'nt it be easier to just lay off the throttle when braking???not sure I understand what this is for??? There are several reasons why this might be a good idea for a bike. 1. Will shut off cruise control when braking. 2. Will shut off motor during panic stop when you might not...

I'm currently using a pair of lights like these: HK055-4h.jpg One is round for a high beam and the other does a line for low beams. The low beam works ok for lower speeds but not so good above 30. Right now I have it set up where one or the other is lit but I may try it with both on for high to get ...

Deja vu! I was at my local sporting goods store today (http://www.dickssportinggoods.com/family/index.jsp?categoryId=15847826) and I looked at that very case! I can't compare it to a pelican brand as I've never seen and inspected one, but from what I've read, the pelican case is pretty beefy allowi...

Here's a very long thread on the GNG: GNG, 1000W 48V BB-drive, $400

There are a couple more in the ebike non-hub section with that one.

Gary

Here's a case that's similar to the storm version of the pelicans. It's an SKB brand case that I purchased here: http://www.casesbysource.com/product/skb-waterproof-case-empty-3i-0907-6b-e SKB case 1.jpg I'm just tossing this out there because you may find the size you need in this other brand.

A buddy is looking at getting an electric bike and asked what I thought of these in aliexpress: http://www.aliexpress.com/item/HPC-F1-TORNADO-ELECTRIC-26-BIKE-BICYCLE-5000W-POWER-SYSTEM-21-FRAME/690213374.html I said that it looked massively overstated in terms of power and range- 5kW out of that h...

As we all know, hydraulic brakes have a better braking performance than mechanical brake.Too many E-bike fans would like to use hydraulic brake replace of the normal brake. Usually we met some troubles in the process of their hydraulic brake conversion with papamotor kits. 1 Hydraulic brakes can’t ...

I think he has a Bafang BPM hub motor.

I need some 72v relays to power my lights/horn... (the handle bar switches are too small) but can't find any... anyone have a link ? (24s so I'm 89v hot off the charger) Relay? Are you needing to switch 72 volts on and off from the handle bar? Or do you need to convert the 72 volts to 12 volts that...

Many of us who've been thrown from our bikes at speed wind up with one of these - photo.GIF Do you have a noticeable bump on top of the affected shoulder/clavical? My Ortho told me practically every pro Hockey player has one on each shoulder. There are surgical solutions but since I don't model or ...

With the regeneration on the disc brakes are not even close to the temperature they where getting.Works really nice and its kinda super emergency braking if you have some speed. The only bad thing with this technology in my opinion is that you have to restrict the (electronic braking , regeneration...

I too just did my first wheel build. I did a BPM CST into an older mtb rim. I ordered spokes for single cross with 1mm long for one side and 1mm short for the other for dishing. First attempt I alternated spoke head direction but since it's a rim brake setup this did not dish it enough so I changed ...

I've been running a Cyclops on a WTB 21-559/26mm wide rim for a while now without trouble. I just make sure it's seated right and stays at least 30psi or more so it stays put. It is a double wall rim but if your single wall rim is strong I don't think there should be a problem.
