This one looks quite compact for 20Ah, but its LiFePo4: 115 X 185 X 260mm. 7.5kg

cringe!!!!

That the Howard Hughes MkII init? :D Not the prettiest bike but you have to admire the engineering and work he's put into it.. why not just fit a hub motor tho eh.

That's a good performance..do you use pedal assist at highest power level? I always say unless you need the capacity for distance/speed or hill climbing don't waste money and add on unnecessary weight with big batteries.. 10Ah will perform fine for most people unless you're very heavy and/or...

I just spotted this intriguing build on endless-sphere while researching freewheels and gearing.. The guy used a motor from HobbyKing and even built the freewheel himself (laser cut then drilled out the teeth himself)! Look at the low-weight (665g) of this $69 69amp 37v 235RM motor from...

Dave do you reckon it would run the e-bike battery down significantly if you took the cells out of that and put a small voltage inverter inside and ran it that way? I guess this thing slides on and off easily off and batteries are easy enough to charge so probably not worth the hassle anyway?

Yeah I'm tempted to get one myself as where I ride it's pitch black there's no lamps at all through some parts, so I generally stick to the bus route lane which is well lit.

I think on a self-build it would be nearly impossible to prove when the throttle was fitted post-law change unless they asked you for some proof of purchase of throttle dating before the change.. but on new bikes sold with a throttle after the law change it would be more straightforward if they...

Howard Hughes the eccentric Texan billionaire created an electric bicycle as a teenager. Maybe he was one of the first ;-) And here it is:

Can you get bottle bottles in 20Ah now? I've never seen them that high capacity..most I've seen is 10Ah.

That looks really good it lights up the path nicely, and not tooo expensive.. I've seen some similar being sold by BMS I think for about same price $50 I think. Why do you think it says don't use too long in high power mode? Battery would run down too quick? I doubt LED's would be a heat...

I think you would still be able to use panniers yes. You can see the racks on BMS tho and they might give some technical info so you can assess if panniers will work before you buy. The sliding under rack mount is probably the best way to mount a big 20Ah battery because of the size and...

Phew sounds like you had a narrow escape there. I think we should give more thought to our lighting and visibility now its dark nights.. yesterday I went out for the first time in 11 months and forgot to check my batteries in my lights, they looked ok when I set off but by the time I was heading...

That's exactly been my experience..once I raised the saddle a couple of inches or so, pedalling become easier and seemed more efficient...the ride felt altogether different and my riding position changed. I'm interested now to try it higher next time and find the optimal level.. my Mezzo saddle...

Wow that's pretty clever! How does it get its power source, from some brushes or something presumably?

I want to buy all these lights and compare/review them :P
