Can't you select level 4 or 3, 2 or 1? Level 5 only allows full current when you're going slow. When you get up to a certain speed, you will see the power start going down. the only thing that causes over-cooking is going too slow up long hills, unless you have a high-speed motor.

You can forget about that. instead, you need to worry about the torque on your axle. The regen torque is much higher than the motor driving torque, so you need really strong reinforced drop-outs. The next problem is the current going into your battery. Ebike batteries are not designed for high...

Halfords discounts often go as high as 20%. They normally happen on bank holiday weekends. unfortunately, you missed the last one. Next one will probably be Xmas.

You can test everything without opening the motor, and it's not very likely that the cause is inside the motor. Do you have a multimeter. You most likely won't be able to solve the problem without one. In the meantime, have a close look at any connectors on the motor cable all the way to the...

There are lots of versions of Giant Twist. Show us which one you have.

Cut the connectors off. red to red, black to black, white to green. Solder and heatshrink. You can use tape, but it looks messy. There is absolutely no point in buying any connectors. it takes much longer to crimp or solder the pins than it does to solder the wires, and you end up with a less...

Be careful when people say things like that. They forget to mention that they only weigh 45kg, or they live in Norfolk where a big hill is about 3ft high. With full sized wheels, one of those motors at 36v and an average 14 amp controller is about right for an average not very fit person that...

I have something similar. It's OK as long as the road is flat, but it soon runs out of puff on hills. the Pedleton Somerby is £739 or lot less if you buy it when they offer the discounts. It has gears to help you keep your pedal speed right and 50% more power.

As far as riding normal ebikes is concerned, they are!

Picking on a single failure mode, which is somewhat less likely to happen than getting run over by a bus doesn't add any strength to your argument. Hydraulic disk brakes are not more complicated, nor more failure prone than rim brakes. They have fewer moving parts and are virtually maintenance...

You have two choices to fit the battery. You can take the plastic cover off the receiver and drill through the aluminium in the right place for the bottle fixing , or you can add your own 5mm rivnut that you can buy on Ebay. For the latter, you have to drill your frame to fit it and you need a...

You need to tell us which pedal sensor you have, whether you have a throttle, which controller you have and of course, which motor. The settings will be different for different systems and how you want the throttle and pedal assist to behave. C1=4 doesn't look right, but I can't say without...

Em3ev is a good source for stuff like that. they've probably got everything you need. their quality is very good and they've been a recommended suppler from the beginning of ebikes. 150km and 80km/h are just not going to happen. you can have one or the other. to do 100km with an average speed...

As Above, and to confirm, 7 amps is the rated current, which is fairly meaningless. The maximum current allowed will be 14a or 15A. there is no legal limit on power from the controller, so you should set it back to where it was unless you actually didn't want that much power. You should set...

I've never had to adjust it yet.

Look for any cheap bike with a conventional triangle frame and disc brakes. A steel frame would be ideal, but alloy is OK. You can then put on whatever kit you want. Don't waste money on an expensive donor bike unless it's only to get one that fits you nicely. The cheap bikes work just as well...

You just replace the stem clamp bolts with two lever bolts, which you can get from Ebay. If you take one of your bolts out and measure it, I can give you a link to an exact replacement. This is the sort of thing. Half a turn with each lever unclamps the bars and allows you to turn them...

Do you know roughly how many equivalent full charges you got out of the Multistars and how many the Turnigys have done? Or how many miles?
