or buy this one from BTN and tell them it's for your BBS01, it comes with the right connector: http://b-t-n.en.alibaba.com/product/1471781843-220560401/BTN_electric_bike_hydralic_bike_brake_sensor.html

I'd have a word with the guy who did your spokes and go watching him fixing your wheel. It takes seconds to check the spoke tension. Did he check the tension of each spoke? if so, what was the spoke tension? If your rim was slightly wonky, the rebuilt wheel will settle down after a few miles...

then you should offer your service to members who just started and don't feel confident enough. If we have about 10 fitters spread out, there should be thousands more self builds. I keep rabitting on about the 8-Fun crank drive kit and bottle batteries because they are the easiest for beginners.

fry it more like. 330RPM with 700C is 43.5kmph. At this speed, the air resistance is above 1000W. The keyde motor uses high reduction ratio to reach 15mph with less magnet than usual, spinning it faster will increase the chance of failure of the clutch unit.

sorry for going off topic. The reason I buy from China is choice. Most kits I found on ebay are poor quality or too expensive for what they are or worse, both. For customers like myself, if there is a reputable UK source for reasonable quality parts then I am quite happy to pay 20-25% above...

I would email XOFO and ask them to make it for me with their saddle bag pack. El Champiero posted on another thread http://www.pedelecs.co.uk/forum/threads/aftermarket-non-genuine-bosch-battery-received-for-testing.17021/ Fine Dragon Technology may do bespoke batteries. It's not advisable to...

If you are going to fit a crank drive, you would lose the chainring, saving a little weight. I was thinking of using a 2kg saddle bag battery (10s3P with Panasonic 3400mAH) - the whole bike should weigh under 15kgs with a 35 mile range.

You could consider the $90 350W MXUS XF08C as a possible candidate. It's the cheapest option (8-Fun CST, Ezee, Xofo XFVK) 270RPM for 700C wheel and 300RPM for 26" wheel for 22-23mph. Any kit is limited overall by the lowest common denominator: motor RPM, battery continous output and controller...

recipe for under 15kgs e-bike: Buy this 8kg carbon road bike from Rutland cycles for £675, add a $400 kit then you have a very light weight ebike. Why the drama?

flecc probably meant that you would fit the motor to the suspension fork if your bike has it, then there is no reason to think that the frame would fail. Going back to very light weight e-bike, it seems that carbon frame and carbon forks are necessary to keep the weight down, then the obvious...

can you remember how much you paid for your XOFO CST?

then there is only one practical solution for very light weight bike: crank drive.

it's a shame that Lishui stops making this integrated controller + LCD: http://www.lsdzs.com/e/ProView.asp?ProId=341 that would simplify the wiring so much. "why a box instead of a water bottle?" I would prefer using off-the-shelf components - you can buy the box today, no need for...

Are there good alternatives to 8-Fun BPM-CST?

The xootr battery case is spendid, made for the job. A square bottle is possibly a next best thing for standard diamond bike frame. It has better occupancy rate than a cylindrical bottle. Like this one...

I would have thought you would be better off using a square bottle battery (Chinese call them flat bottles) - the case can pack 50 cells or 40 cells + controller. Why 48V? 36V with more Amps will do the same job with a lot less hassle (eg a 36V battery cannot kill you but a 48V battery can)

Jerry, do you know any good motor that would fit the front fork of this this Globe Works 3?

amigafan2003 has Panasonic 3400mah NCR18650B's sitting in his fridge. Those are 49g/pc. The strong point of the annad design is stealth. Are there enough customers wanting to pay £500-£700 extra for this? I think possibly but it's a big risk.

I think they run a 33V (9S) system - due to the space limitation

I can still remember my old watch fogging up. This problem has been solved long time ago by the watch industry with a better seal. The glass on the LCD is simply glued to the plastic shell, there is a little rubber gasket between the glass and the plastic shell but the rubber gasket is not kept...
