Nice review, thanks. I agree. I think a bike in that price range should have a cassette motor with 9-speed gears.

I collected the Wisper 705 with 575Wh battery from CH White & Son. I previously bought a Brommie from them and they have given me good advice. I was given a wedge for the brake caliper when I said I'd need to take the front wheel out to get it in the car. I think it was last year's model at last...

You're right about being able to get a high mileage out of your drive train, but you must put that in the context of how much power you use or how much range you get from your battery and what battery it is. Obviously, if anyone rode a crank drive bike around with the motor switched off, there...

Hub motors are especially good for hill climbing when you have 20" wheels. From what you've been saying, it's pretty clear that there's a hole in your understanding about how hub-motors and ebikes in general work. A motor is just a transducer. Power is taken from the battery at a rate...

Exactly! TF!! Is it a smidge or a wodge? How much of a smidge is acceptable? At what point does a smidge turn into a wodge? Does a smidge become a midge before becoming a wodge? Is a midge going to get your battery confiscated? I'll flatten it again then, or order another one for the...

Hi All, I have been a member of the Pedelecs group for many years and have been more than interested in E-bikes ever since my visit to the Tour of Presteigne when it was a thing! They have come on leap and bounds since those days! To cut a long story short I am awaiting knee surgery to...

I don't agree at all. I say put the label on the motor. As long as any third party can see the label when you show them where it is, it's compliant. If asked, just spin the wheel round until the label is upwards, then point to it. If it's covered in dirt, wipe it with your finger. In the...

I can, but do I need to? I was thinking this is more of a generic/general thing, than an equipment specific issue? I did do a little reading about cadence vs torque sensors before I asked about the symptoms of each. Does the Min/Max refer to the potential amps available to the motor? I only...

Generally, you can put any crank on most bikes. I often swap for road bike ones because you only need two rings when you have a motor. They're lighter too. I think I have 48T/34T on mine.

Great idea, but it won't because it gives the wrong type of signal. The torque sensor has four wires to tell the controller the speed of crank rotation via a high frequency pulsed signal and a displacement (torque) via a 0 to 5v analogue signal. A pAS sensor gives a relatively low frequency...

Thanks for the reply. The torque sensor is completely destroyed with no hope of revival. In my logic I was hoping that replacing the crank and using a normal pos sensor kit and changing the plug to fit the controller it would in theory work the same way. Would measure the revolutions of the...

The sensor is screwed to a stationary part of the chainwheel. There are two lugs on the sensor that fit either side of a fixed stop to prevent that part of the chainwheel from turning. The crank mechanism is extremely wafty. The fixed and moving parts of the chainwheel are separated by a thin...

Each time you do the self-learning, the motor reverses direction, so do it again. Make sure you disconnect the wires before switching back on.

sorry its me again fitted the new pas glad i did as the old one was cracked around the magnets. put everything back together joined the learning wires powered on, the wheel spun up in the right direction, powered off and disconnected the learning wires. powered on and rotated the crank but motor...

All what these guys are saying is what you have to do for PERFECTv shifting, but whatever you have, as long as you get bottom and top gears correct, it'll work. I've used 7 speed freewheel with 9 speed shifter and derailleur, 8 speed freewheel with 6-speed bike, and many other combinations...

Hi Denwyn, have you considered our new Tailwinds? We are getting amazing feedback from owners. This is the stripped back City model a low crossbar comfort model with mudguards etc May suit you better. Also available in black. All the best, David

After a lot of though i have decided to buy from local dealers, my partner bought a new Wisper 705 T last week to replace her faulty 705T which was going to be to expensive to repair. I have a 705 T which is absolutley fine but i fancy a change, not another 705T, after much thought i have...

You can have a throttle that works independently up to 4mph, and regualtes the speed or power above that while you wave the pedals round without effort. The only rule is that the power must stop if the pedals stop when you're travelling above 4 mph. The advantage of a throttle, apart from...

Thanks for your response, that's good to know about the battery. Yes, I don't fold it as it is, I have a skoda roomster with the seats out so I manage to fit it in upright with a little jiggery pokery. But I do wonder if the added weight will just make it prohibitive, in which case it would make...

20" bikes are not so good with a crank motor because you need a big chainwheel. Hub motors are better anyway. I would never fit a crank motor to a small-wheeled folding bike. it doesn't give any advantage over a hub-motor. You're starting to over-think your idea. Just do it, and you'll be...
