Again many thanks for the leads etc. This is what I have come up with, two options for a DIY kit as follows: Option 1 BMS Battery Q100H 36V350W 260 rpm Rear E-Bike Motor Wheel 20” £80 S06S 250W Torque Simulation Sine Wave Controller £20 S-LCD5 LCD Meter for S-Series Controller £14 Eight...

Thanks chaps, I'll come back with a proposal for your comment.:rolleyes:

Perhaps what we need is a solar version and a network of epowered vehicle paths. It can all happen if we want it to, considering the £££$$$£££$$$ sums used to prop up the banking system a few thousand miles of e-paths is not a big deal just need to find the will .... if we could get the city...

Not easy I suspect. I read a recent motorcycle review that had vibration through the footpegs that a very similar version of the bike didn't and it came down to the foot peg hangers acting as a tuning fork in sympathy with the engine, only fix was a redesign of the footpeg hangers :(

I'm having success with the 24V version on some hilly areas, not sure what the 36V version gives you over the 24V perhaps more acceleration and a lower motor current? Running the 24V motor at 36 Volts would allows me to get useful drive at 20MPH rather than the current 17-18MPH as this would...

Flecc thanks for the comments it did turn out rather well.. This is the 24 volt kit that comes with a battery and battery bracket that attaches, in my case, to the seat post. The bottom of the battery bracket forms a small box when the supplied side panels are attached and this is where the...

It was easy to fit for my bottom bracket, I had to remove the crank to fit the magnetic ring sensor, just pushes on the shaft and the lock nut on the bottom bracket had to be removed to fit the pick-up. So for this type of bracket you will need a crank tool about £8 and a "C" spanner £? Not...

frank9755 that's a good point, even 10MPH can be too much assist when manoeuvring through subways etc. :eek:

A few photos of my bike: Bike and installed kit Pedal sensor Front fork widening

Yes "The Maestro" has it. I got the sensor and magnet ring with my kit so since I was having problems with my bottom bracket, fixed the sensor at the same time as the bearing repair. Did my first commute today, max speed I can maintain without breaking a sweat on slight undulation is 16-17...

I just used the ebay email seller link and got a near instant reply and follow up to a few questions. I live in Basingstoke where are you?

No that is max speed with the pot wound fully clockwise as per instruction sheet :)

More info about the Alien 24volt 20inch installation in my Dahon Speed D7 folder: Took the bike up and down a hill, total distance 3 miles average speed 13 MPH, max speed 25.5 MPH. This was in max throttle down the hill and pedelec mode up the hill for the majority of the time (just gave it...

Just a quick note to let you know that I completed the installation of the 24V 20 inch kit to my Dahon speed 7 folder this evening. I'll post more details of the installation with pics later but just thought I'd let you have my impressions of my first short ride. It is now a heavy bike but I...

Alien 24 volt 20 inch kit - Dahon folder I've just received the 24 volt 20 inch Alien kit and I'm in the process of fitting it to my Dahon Speed 7 folder. I fitted the hub motor to the front wheel last night and fitted Big Apple tyres (thanks Flecc). First impression was this front...

Thanks John, simple sounds good I'll try something with switches and resistors first..

Hi, Inspired by the throttle of the Cytronex I was wondering if anyone has built a similar device? I would like to have a two speed setting, low speed optimised for max hill climb support (on a 20inch folder) and one at max speed. I'm thinking I could use the throttle input to the...

Nice looking kit... Thanks for the review it came at just the right time, I've just ordered the 24volt 20inch kit for my Dahon folder, I'll let you know how I get on too. Jusrt for clarity, did you adjust the pot on the blue wires or remove it all togther?

Thanks flecc they look the job, any suggestion on pressures the spec says 30 to 75psi?

...good point but a Bionx is tooooo expensive and not over here so perhaps a fatter front tyre may help?
