You lucky bugger! I paid £150 for my bike but I've been selling off all the parts I'm replacing so I will get a bit back. When I finish this I want to build another folding bike something smaller and more portable with 20" or maybe 16" wheels.

Sensor Success! I managed to get that crank fixture off with the old hammer and screwdriver method, came off very easily. I put the sensor behind it and put it back on and tightened up the same way I took it off.. put the magnetic disk in place as close as possible about 1mm gap then...

Thanks Flecc, something to add to my growing toolbox.

Aha many thanks Frank. I will try your method and see how I go. That is what makes this forum so great..always someone knowledgeable on hand to answer any problem!

Help! Sensor problems I have just taken the crank arm off with the help of my little crank puller but I'm completely stumped as to how to attach the sensor. I think I understand where it needs to go, which if I'm right, is where I'm holding it in the picture below? But how do you get it to...

My frame and the forks are made from steel I'm told..I don't know whether that is normal steel or some kind of steel alloy. The bike itself weighs 14.5kg which is quite light for a full size bike. The fit in the drop outs is very snug indeed, so perhaps that and the steel forks will be...

Hi Chris, thanks. Great bike. I actually planned to buy an Espresso myself as it seemed the ideal bike to convert.. but then I spotted this Chinese copy of the Espresso which was considerably cheaper so I took a gamble and got one. The frame is all that's good about it, so I'm upgrading nearly...

handlebar space One thing I did have a problem with was fitting the LCD and throttle onto the handlebar. Being a folding bike it had a shorter handlebar and the twist gears eat up a lot of space so I couldn't fit the throttle on the right side where I wanted it.. My solution was to remove the...

Jerry, do you cycle in the rain much and how does your bag cope is it water resistant? This is one thing which worried me a bit..I was looking for a waterproof bag and contacted a few companies.. one German manufacturer of bags told me that no bags are 100% waterproof due to all the stitching...

Ah, of course. I did set the 26" wheel size on the LCD menu but there was a second option for the tyre size I think which I had left on the first setting. I just checked again and I have 2.1" tyres so I adjusted the setting. I wonder how much difference that will make.. The brakes were indeed...

Hi Jerry, you're right the controller is in the bag with the battery..it's only a little controller..the bag is the perfect size and only cost a fiver off eBay. I also managed to cram all the cabling in there but it's very messy and will need sorting out. I agree with you on the umbilical...

First test ride! Well I couldn't wait and decided to take the bike out early this morning for a quick test ride before I had fitted the pedal assist sensor... Ruddy hell it was cold. Wish I had taken my gloves my hands were froze! Anyway back to the test ride... I tried pedaling the bike...

Many thanks for the info the battery charger had me puzzled..how long does it take normally for yours to reach full charge once it starts alternating? The charger is a bit of a brick isn't it!? Do you know if it's safe to leave the battery on for longer once the LED is permanently green?

Quick update I've finished the wiring this evening after installing the battery and controller onto the bike...found the wiring a bit confusing at first as I had to work from a diagram which had some variations in colours. I also had to fit an IEC power connector to the controller power leads...

Interesting, so I guess it varies a bit depending on the controller.. I will have to carry out some tests and see if this controller is any good then report back.

Jerry, I forgot to ask..are those little torque washers sufficient then to manage the torque from 250 36v motor on a 26" wheel in your opinion? I've seen other posts recommending more substantial torque arms and brackets but I think they look unsightly and would prefer the washers.

Am I right in thinking that this sensor is used in establishing the normal 15mph speed restriction in the controller? I.e. when you pedal above a certain rpm the motor cuts out? Or is that normally done by monitoring the motor itself? There's three wires from the sensor, one is for speed...

Ah thanks for that. Will have a go at getting it installed tomorrow when my crank puller arrives hopefully.

Hey nice quality video there Allen, amazing for such a cheap camera. Camera movement is not too bad either. I tried filming with my little Toshiba Camileo flip camera once, phew..terrible camera shake and virtually impossible to hold while riding. I did consider making some kind of handlebar...

I just had a look again at the washer and axle, and it looks like its only a mm too small..so maybe filing is the best way.
