I don't quite agree with this reasoning. Hub motors are not so good with very steep hills or very heavy loads. Their minimal recommended speed is typically around 8mph/110RPM. Below that RPM, the hub motor will likely to overheat when hauling a heavy load up a steep hill. I think you need first...

That's not correct. The power comes from the controller and would be the same no matter which motor you have. I think you mean torque. With a crank motor, you can trade speed for torque using the gears. Torque affects how steep you can climb. Power affects the speed you can climb. Be careful...

Not all ebikes are the same. Some are designed for commuting, some for city riding, some for touring and some for specific things, like riding off road, mountain climbing, going fast, easy to store, etc. Those things are not mutually exclusive. Every bike can do all of them to a greater or...

Some bikes with cadence sensors and hub-motors are terrible, others are brilliant. The Bafang BBS01 has a cadence sensor. A lot of people like it. I think I prefer it to the Tongsheng for a long ride, especially long hills, but my hub-motored bike trounces both of them. I have an AKM 128 motor...

I suppose mid-motor with torque sensor is what I'm used to. I bought s Tongsheng mid motor and have fitted it to 3 different bikes now. I have ridden a cadence sensing bike and didn't like it at all. When starting off,and when toiling up hills at low revs - just when you need a lot of help...

Bizango is not the best donor because of the small chainwheel. When you have a motor helping you, your gearing is going to be too low. Personally, I'd forget it, and get a bike with a normal sized chainwheel, then you can fit whatever kit you want and enjoy relaxed pedalling at whatever speed...

Not speech in this case, but freedom of action is being targeted, by the likely demand that people be prevented from making their own conversions. Freedom, or the lack of it, is not just about speech and opinions being prohibited. It is also about whether the state interferes with what you...

Thanks guys so I have started the build on the Spezalied 28 inch light weight that I will keep . 250 W YOSE rear wheel drive motor left over from Carrera build , I will use a KT controller as per your advise. not sure yet how as to battery position and type Frog, Down tube or rear rack. The...

I've started with some improvements to make the bike a bit more useful for me. Its main problems are the too low gearing and the lack of torque. The weight is also a bit on the high side. Most of the weight is in the frame, so not much can be done about it. If you were serious, you could change...

It already is an epic fun ride. I have just been riding mine another 15 miles around Hadrian's Wall. I'm grinning all the way. One of my neighbour's - a lady of a certain age has begged a 'try' from me and thinks it is fabulous. You just have to adopt the philosophy of. 'It is what it is.' It...

That is a good long run Matthew. Have you had to re-grease the motor and its reduction gearbox / gearboxes? I wonder how long my Bafang BBs will go before I need to intervene with it and put some grease in. I have nowhere near the mileage that you have built up. Just a couple of thousand...

After 3 years and 17,700 miles, my Shimano e5000 is still without any crank play. I have a spare motor which does not need any dealer intervention to fit, and which crop up from time to time on eBay for under £200. I should be ok for a while yet!

You will not get another 5000 miles out of it. As soon as you get any play in the bearings, you must get it fixed, otherwise the damage accelerates. You can also get a bearing and seal kit and repair it yourself, though for the difference in cost, you might as well send the whole motor to...

My pennies worth: BEARINGS SERVICE If you went for a bearing service and from what you say above, around 15,000 miles will get you another 4yrs cycling before you're back to where you are now. In that time your bike may develope a different issue or indeed the battery (at £500?) may need...

After 4 years and 15,000 miles, my active line plus has developed a significant but not terminal amount of play in the crank bearings...these are my options: Send to performance line bearings for a full service circa £275. Run it do death, I'm thinking another year circa 20,000 miles....buy a...

Why did you replace the sensor? Is the cable OK on the other one? If so, you can swap them over. IIRC, there's a connector at the sensor end that burried in rubber sealant.

Hi Saneagle Thank you,i have replaced display, ecu, crank sensor and rear motor,am getting 41.3v out of 36v battery so only thing it could be is this cable i think.Would have to cut possible bad bit out and reconnect.Is there an easy way of re-connecting cables back together Thank yo Ian

It's almost certainly a cable connection issue. It might even be that the cable has been pulled at the sensor, so one of them has broken its connection. The sensor itself is optical, so nothing can go wrong with it, other than after a lot of use in dirty conditions, the dirt can stop it seeing...

Hi all I took my carrera vengeance e spec bike into an independent bike shop recently after losing faith in Halfords after countless visits.Anyway i was told the problem was an intermittent crank sensor.I'm not getting pedal assist but when i turn bike upside down and turn pedals i can hear rear...

Must have been badly out of fettle. Those old two strokes should just start straight away. Of course there are lots of issues in worn, and neglected 2 stroke engines. Bad petrol, coked up spark plug, wrong spark gap, wrong points gap, dirty points, duff condenser in points, bad ht lead, low...
