The 48V TSDZ2B that I sell has a full throttle. Head over to https://wooshbikes.co.uk/?tsdz2 for details. If you want to climb hills without pedalling then use the throttle.It's possible to get the BBS01B motor doing nearly all of the work, by pedalling too slow using the absolute minimum pedal push force possible on highest assistance (firmware tweak "Keep current" at 100% helps). I don't know if similar can be done with the TSDZ2 because I've never tried one, and certainly will never buy one.
3K is a lot, a sum like that burning a hole in my pocket would likely get spent on an actual IC motorbike.I decided to build an electric moped. Picked up a 39 year old frame with a v5 from an auction last week for £170 plus buyers fees. So no mot required after next September and free tax the following April.
Most of the stuff that came with it was junk and has gone to the recycling centre, including the engine and exhaust. Nice 5 star wheels though. Shame I can’t use the back one.
It‘s going to get a rear hub motor. And a 20s 10p battery where the engine used to be.

The Q128H from BMSBattery is supposedly rated at 800w. It's actually the same size as your average 250w motor, so would easily pass as one, especially if the easy-peel label fell off. It's a freewheel hub, so limited to 7-speed, but that's fine considering how much power it can give. At 14A and 48v, it gives enough power for what any normal rider would need on normal roads with the occasional steep hill. At 20 amps, it should have enough power for heavyweight riders to deal with steep hills. 25A would be overkill for most riders, but it can easily handle that much power.After getting myself hyped up for a torque sensing mid drive, i think i am actually more inclined to go for a rear hub, i have just about managed to get away with 2 bikes being kept indoors a third would be the straw.
That being the case it would be my Fiido d4s that would get the chop so i would be without a rear hub powered bike, i have my bbs02 for long distance fair weather cruising so this will be my everyday all weather workhorse.
So with that now established in my mind any recommendations on a waterproof 750w 48v reliable rear hub kit.

So I have a Cannondale EQ Adventure step thru arriving in about a week and haven't decided which kit to put on it yet, I do know 750w is my sweet spot and I rarely go above 15mph but need the oomph for a steep hill I take a few times daily .
What I'm looking for is suggestions for what you would put on it and how as in positioning of kit components for as neat a look as possible.
Bear in mind I am not overly keen on rear rack mounted batteries and do have a brand new 17.5ah 48v Hailong battery lying around unused from my previous project.
Aha! Found @saneagle's post about the Xiongda 2 speed:Just read this very interesting thanks
I did a complete test and write-up back in 2014:
Did you receive your bike? I got my delivered yesterday - what a traumatic experience. I don't think I will order anything big from Evans Cycles anymore.So I have a Cannondale EQ Adventure step thru arriving in about a week

Red color is absolutely beautiful.
I am a bit disappointed with Micrishift derailer. At this price point I was expecting better performance. It might make more sense to use rear hub rather than mid drive.
Funny thing - kick stand is to long. That I didn't expect LOL
Hi all after going to bed with my mind made up on a Toseven, i took my rear hub out the next day and had a change of heart i have a mid drive already so i would like to go for the rear hub i have found the following after much searching as i would like a bafang and the 750w rear hubs all seem to be fat bike centric.
So would the following kit be suitable for the Cannonndale Adventure Eq
If it is suitable would i be able to use it in conjuction with the torque sensor kkit from Whoosh.Bafang G0900 48V 750W Rear Cassette Brushless Hub Motor 26“27.5”700C Bicycle Conversion Kit With LCD Display For Eroad - AliExpress 18

That kit has a 22A controller. Woosh one is only 15A, so not much point in having a motor like that. Why not get a Q128H motor and KT controller and be happy like Neal and I and everybody else that uses one? I can't see any advantage of a torque sensor. Have you tried a KT controller yet?Hi all after going to bed with my mind made up on a Toseven, i took my rear hub out the next day and had a change of heart i have a mid drive already so i would like to go for the rear hub i have found the following after much searching as i would like a bafang and the 750w rear hubs all seem to be fat bike centric.

I can send you one to try out if you like.I can't see any advantage of a torque sensor. Have you tried a KT controller yet?

At 20 amps, it should have enough power for heavyweight riders to deal with steep hills. 25A would be overkill for most riders, but it can easily handle that much power.
If you must have 8-speeds or more, there's the Q128C, which can handle up to 22 amps. It's a bit narrower than the H version because it needs more room for the cassette. It's a bit wider too, so you have to spring the frame a bit to get it in, and you normally need to off-set the rim to get it central.
Whatever motor you get, make sure you choose the right speed version. Its max RPM at the voltage you run it should be approximately 1.2 to 1.3 times your planned modal riding speed.
If you get a nice KT controller, you don't need a torque sensor. If your only experience of hub-motored bikes was a Woosh, Freego or similar with crappy LiShui controller, I can see why someone might think about the advantages of a torque sensor, but I'd say a KT controller is a better solution as it gives more choice of how hard you need or want to pedal.
Thanks for the reply, I've spent the past few hours reading up on the Q128H. I think it would actually be the best option for me, small enough to be fairly inconspicuous and lighter then most other similarly powered motors.I did a complete test and write-up back in 2014:
I can summarise by saying the 48v version is like a winch when it comes to hills. The internal shifting takes a bit of getting used to. On automatic, it often shifts at the wrong time, so it's better to shift manually. It'll cruise happily at 20 mph in the high gear, and it can manage moderate hills in high gear, like any similar sized hub-motor, but in low gear the torque is immense, and speed can go well below 10 mph without over-heating.XiongDa Two-Speed Motor
I started a new thread with a new title so that it'll e easier to find in a search. The motor weighs 3.283kg. It's the same size as a Bafang QSWXK5, The spoke holes are on the same PCD too of 120mm. Here's a photo of it next to a Q100 that has its spoke holes on a PCD of 108mm: The thread...www.pedelecs.co.uk
It's pretty wide, so you need to spring the frame a fair amount to get it in and you need to build a large off-set to get the rim central.
In summary, I'd say that the Q128H is better overall because it's simpler, easier to install and it can give enough torque for just about anything. The Xiongda might be better for towing because it can run slower.
you can get a BBTS kit with DWG22C wheel in 650B rim for £260 from me.So I'm going to need a Q128h ready laced into a 27.5 diameter wheel a recommendation for a decent controller to make the most of it all I have a half twist throttle unused also from aforementioned build also what would be the best display to go along side it, it would be great if someone did a kit with everything I'll need.
I have the 48V G020 /SWX02 (12) with 26 inch wheels, with the cheapo standard speed based 18a controller (just in the process of moving to the Woosh torque based kit) . I thought it would be a good compromise between speed and hill climbing ability. I did consider the (10) - that is 393 rpm on 48v ? Not had any problems up some pretty severe hills (see below - which did cause the xf08c 36v to stutter !) and seems to be in the power band at legalish speeds (max unrestricted motor no load speed on full battery 28mph) - which is faster than I would want to go !I like the Bafang GO20/SWX02 (10). It’s small, lightweight, cheap, reasonable quality, readily available and can be run at ridiculous power levels with a few modifications.
It also has good spare parts availability, so if it is abused the clutch and planetary gears can easily be changed at little cost.
And in the event of overheating it is easy to fit the innards of a new one into the case, so you don’t need to lace up a new wheel if you blow it up.
