You need to think about where you're going to fit the battery. The best place is low and central. The Paratrooper can't really do that. Yes it can be done, but wouldn't it be better to have it nicer if you can. Donor bikes are really cheap considering the cost of the kit. It's worth getting the...

Unfortunately, you have that incorrect. You need power to climb fast. Power = torque x speed, so if you use a crank-drive and small wheels, your torque goes up, but your speed goes down. Let's say, you have your 36v motor's controller set to the default 15 amps. That's 540w from your battery...

Whatever NM my cadence sensored 720W BBS01B exerts on the road via my 20" rear wheel, I reckon power isn't a million Watts away from @saneagle's 48V X 22A = 1050W hub motor via his larger rear wheel. Untrue! I can climb hills faster to escape your unhinged mates!

I meant from a standing start. Once moving there’s no problem. Didn’t happen every time so I suppose it just happened when the ratchet in the cassette and the crank had further to turn before engaging.

My reaction too. Mine comes on softly, gradually increasing torque over about a second or two. Perhaps Steelframe, means the unpleasant effect of changing gear while applying power. Imagine doing that in a manual car. Properly set up, power stops when you stop pedalling. Mine stops in a...

It doesn't have 80Nm. That's just an arbitrary number for advertising. The actual torque depends on your gearing. You can get 1000Nm if you want - just lower the gearing. When you've ridden a load of different bikes with different motors at different currents and at different voltages, you get...

Hmm! The thing about hub-motors is that they're are many different types to meet different needs. Sure, if you're average weight riding on average roads for commuting or touring, most common hub-motors would work for you, but the moment you bring in special requirements, you need the motor that...

Hm, sure? Only 3pins on my bike, but if I bypass that, my question is how the bike will behave on 24V?

IIRC, the Panasonic crank-motor won't run with an ordinary battery. It has to be the Panasonic one. Try german Ebay. There's usually a few large capacity ones there. Search for "Panasonic akku"

I think they call it blissful ignorance! Actually, my comment was addressed to my friend Guerney. His bike has 20" wheels, which swings things significantly in favour of a hub-motor. There are some cases where bikes or riders are more suited to crank motors, but generally not for a touring or...

Yes - the rear suspension of that Scott Genius has 3 settings that you can adjust from a lever on the handlebar : Locked (a bit pointless for me), Downhill (6 inches of travel) , Traction Control (4 inches of travel and compression damping increased). I think I will leave it in Traction...

If I were you' I'd buy a new BB. You can get them from Halfords for about £12. See what lengths they've got and get a longish one, which should have enough room for the pedal sensor on one end or the other. Actually, you can get a good idea of how much room there is by looking at the parallel...

Don’t forget the biggest problem is there is no original battery with the bike and a refurbished one is around £480.00 plus £100 0dd for a charger Phy Lion Batteries even after market with BMS in Holland for example are still over 400 quid around 10 AH so poor range Ok so BMS is an...

No the rubber thing does not come off easily but if need s be I could cut it away to expose BB The out side diameter of the BB is 22mm. Is this a further problem ? And it looks like it’s longer than it needs to be for a standard Crank the PAS sensor s I have looked at are over smaller than 22...

Good. Next time someone with a full suspension bike comes on here asking about how to convert it, you can give all the exact details on how to do it, instead of just telling them to buy your motor. That'll save me a lot of writing.

Tongsheng has made a through axle rear motor. It's now massproduced. It's not a critical issue. There are plenty with 40+T rings. I have a 36V 10AH bag battery on my full-sus bike. I could have had 48V10AH there too. I am not the only supplier of bag batteries, there are others. you can...

Some older full suspension bikes are excellent donors for conversions. If the travel is not too much, the improvement in comfort is worth it for a very slight loss of pedal efficiency, but you can forget about most modern ones because they might have any of these features, which make conversion...

No photos! I'm pretty sure that the Yose motor won't fit the Carrera. Take the back wheel off and have a look on the left side drop-out. Is it special for the Suntour torque arm? If it's a special shape, use the TBK controller on that bike with the Suntour motor and use the Yose kit on the...

Hi Seneagle I checked out the sites you recommended and bought the Control kit from Topbike which when we work out the rest of the kit for the Giant we will use on that to keep. We have decided to get the Carrera going with a full Yose kit including there rear wheel motor and rim and just...
