    My 19 Year old GT MB conversion

    Thumbs up for DIYer's. Lets see some more.... Is 16.7 mph maximum speed? and is that motor only? Lacing a wheel gets easier the more you do. It certainly doesn't look electric. I think my next one will have a rear motor they tuck away nicely behind the rear gears. I like the idea of the cd...

    Front suspension: a 'must' or a luxury?

    Sometimes i wished my bike had front suspension. I've hit a bad bump and nearly lost control when my hand came off the handle bars. But i don't think i'd be happy with the squishy ride at all times. The roads are bad though and the cycle paths aren't much better. The only front suspension i'd...

    i'm seeing loads of electric bikes now!

    There now five ebikers that i know of in Yeovil. I regular meet (catch up) a guy riding a second powerbyke on my way home form work. Another on a yellow Izip, and i have seen 2 more powerbykes from a distance. There is also JohnP who has several ebikes, but he's lives in the countryside the away...

    E-bike prejudice?

    I must admit, i get a little tired of explaining the benefits to people who are obviously blinkered to something (or anything ) they don't understand. Cyclists seem to be on some sort of mission pushing themselves to get faster and fitter. That, it would seem is their motivation. Whereas, i...

    Marin ebike project

    I'm fairly fit at the age of 52 (not exactly young though). I've had trouble with one of knees for a while and i guess it's not going to get any better, 10-15 miles and it starts to hurt quite bad. Yesterdays ride of 25miles and it was fine. Having a small amount electric assist is taking the...

    Marin ebike project

    I was running out of space on the handlebars. A minura space saver was an ebay bargain. This has my current limiter and speedo attached. The turnigy meter is temporarly fitted to the stem so i can monitor Wh's used. The small light is my summer one...it has a fast bright strobe. I found to many...

    Marin ebike project

    So, to the garage and knock up a housing for the batteries. It needs to be strong and more importantly secure, should i leave the bike locked up for any amount of time. I had some galvanised steel to construct a nice box exactly the size need to fit both batteries. Using basic tools and within...

    Marin ebike project

    Hi Everyone Time for an update. Our second Ping battery arrived the other day. One for my bike and one for my wife's bike. Both bikes get used for commuting (albeit not very far) so getting to finish mine off has taken more time than i wanted. This is another nice and light 36Volt 5ah. And...

    Power cabling question

    I have just wired my Turnigy meter to the handlebars. I think i am probably going to get more losses through the extra connectors i have fitted. I have installed it so i can quickly re-connect the meter to monitor power going into the battery pack when charging. I think this can be another...

    i'm seeing loads of electric bikes now!

    Not many around here either, just people moaning about the price of fuel.

    Can i confirm something?

    Fit it between battery and controller. You will need inline connectors, to reset, you disconnect. I used europlugs.

    Tongxin freewheel problems ?

    Thats good Jerry, no broken parts. The worst part of dismantling them is getting the cover off. Once you have done that everything else is straightforward. But I wonder where the noise was coming from?? One thing i did while mine was stripped down was to tighten the axles shaft to the motor...

    Can i confirm something?

    Do you know what power is being drawn from your battery at the moment? It might be a good idea to buy a turnigy power analyser. This will give you some idea to peak current, volt drop, watthours. You may be surprised with the info it will supply you with. They cost around £25 on ebay. My...

    A reminder to look after your chain

    Here's another thought about chain wear. We use our bikes daily for commuting, not very far but nevertheless in all weathers. The chains get crudded up in no time. To be honest, i opt for the easy route of doseing the chain and sprockets in 3in1 oil. Until it's eventually so mucky i can no...

    Marin ebike project

    Thank for the comments. Of all the makes i could have opted for, i am pleased with the Marin. It has some nice parts with it. It cost me £380 which is a nice price for a quality bike as the basis of the project. I already have the tongxin parts. With the nice weather here again, i'm getting...

    Marin ebike project

    Here is my new bike. A Marin Muirwoods 2009 model. I got this at a bargain price and luckily for me it was the last one they had. I like the look and design of these bikes and have been looking at these Urban bikes for a while. It has a lightweight mountain bike frame, skinny kevlar tyres...

    Power used per mile

    You don't have to go to the expense of a CA. I built my own limiter using a shunt and a small circuit to 'clamp' throttle voltage. You ride at full throttle and adjust the power level you require. I made four, two for me, JohnP had one and so did Frank. JohnP reports that it works very well (but...

    Tongxin freewheel problems ?

    Yes it turns anti clockwise. I used some longer screws of the same thread with a couple of nuts to lock the tooling flat onto the cover (if you see what i mean?).I guess the more screws you can use the better chance of removing it. Steels dowels with a countersunk shape would be nice, but i...
