Pat I think with a Tongxin Nano motor and a 36v 10Ah battery, you could easily do 15-20 miles recharging your battery at work providing as you say your route is 90% flat and you pedal assist as well. Probably more so in that I am 52 and weigh just over 13 stone :( With mine (I live in Cambridge...

This is a great post/thread for newbies fitting motors. I really struggled with this stuff when I fitted my first kit. I have only recently started fitting my motors so the cable exits/bends underneath which makes sense when trying to keep water out of the motor, Regards Jerry

Just tried it and as amigaman states lovely smooth throttle with the Goldant motor :) I have to say this is very pleasing as having pedelec only is not to my liking. I need to start a new thread about this controller though I guess I could just go checkout endlessphere. Regards Jerry

Dave is that wheel rolling right to left in the pic and if so isn't the arm being pushed in an anti clockwise motion ? Jerry

I just emailed Ed Lyen and told him what I wanted. He came back with the various options and prices. Email at the bottome of this page LYEN Controllers I got all the options i.e. PAS, Throttle, Three Way Power switch, Cruise Control etc as I have always wanted to play around with the...

My Lyen controller turned up today, lots of wires coming out of it :p Jerry

The Brompton already has rear suspension so little/no point in fitting a suspension seat post. It does not have front suspension though. For long rides I use this 20" bike with front and rear suspension :) Its fine for work commutes as it splits and goes in my office. Not...

For twenty miles each way and throttle only, I would NOT recommend you use either a Brompton or a Tongxin setup. Regards Jerry

Great thread :D Jerry

My first kit was from Alien Ocean back in 2009 and my first introduction to ebikes. My bike conversion (Raliegh Datona) and testimony are detailed half way down their page here Electric Bicycles - Customer Conversions Their service was fantastic. Regards Jerry

lol good point "busted" I can't wait to see what Brompton brings out. Jerry

Yep that looks like the right one though, they have a better waterproof connector now. Just mention to her that you want the one for V brakes (I got a couple of roller brake ones once when I did not specify them correctly which was a challenge) and say its for a small wheeled bike. Cici will...

I discovered glue lined heat shrink a couple of years ago and like you use it often for my Deans connectors. Regular heat shrink just comes away once you have plugged and unplugged the connectors a few times. My top tool would be my bike work stand. I liked my first one (generic £50 one) so...

Interesting looking bike. Being able to fit Big Apples is nice, though I guess with full suspension less important. "With a starting weight of only 18 kg, it is one of the lightest electric bikes on the market" not true that would be a two speed Ti Brompton with a Goldant Motor at 11.5kg +...

Pat email sales@h9.com.cn and tell them what you want. The contact I dealt with was cici. They provide a stock controller that goes with it plus you will need to tell them if you want throttle, pedelec or both. You need a narrow width (80mm) 36v, 260RPM, for V brakes model. Stock they come...

Someone pass me the popcorn :p Jerry

For your requirements you would probably be better off with a Bafang or a Cute motor which would need to be over volted if you want to run at 20mph. The wider 100mm motors do effect the fold as even the narrower 80mm Tongxins do as well. I guess you could still use a Tongxin but again would...

All the links for suppliers have been posted before. Basically you have a choice to buy a ready made kit £700-800 incl battery or source the parts direct from China for a DIY conversion for about 1/3 the cost. Direct from China you will need to be able to specify exactly what you want and have...

I got my daughter to finally shift from an iPhone to a Galaxy 2. My wife also has one. I saw someone at work who showed me their Galaxy 3 and very nice it was too :) Regards Jerry
