Any good conversion kits for a pashley pronto?

://www.pashley.co.uk/products/pronto

I'm looking for a hub drive conversion kit.

 

The wheel sizes = 26" rear 24" front, alloy rims with 13 gauge spokes

I'm looking for a hub drive conversion kit.

Why? Pashley's own electric version of the Pronto model uses an 80Nm crank drive conversion. I'd think they made that choice because the bike in un-electrified form uses a 3-speed gear in the rear hub, and a drum brake in the front hub making it not an ideal choice for swapping out wheel sets. It's also designed to haul 40kg cargo on-bike and an additional 60kg with their trailer, so crank-drive is likely the better choice especially if there are any hills to contend with.

The problem is if you use a front hub motor you will lose your front brake. And a rear hub motor loses both the gears and the brake. I guess it’s why Pashley recommend you to use the BBS02 mid drive.

Depends what you are after. Do you want a road or off road kit?

Road

Yeah, good choice, I’m not sure your brakes and gearbox will cope with 1000watts.

 

Woosh has a good reputation for supplying road legal e-bike kits, both hub and mid mount, so you have a choice between bafang and tongsheng depending upon if you want cadence or torque pedal assist. If you are a lazy rider like me go for cadence and the BBS01. If you want a bit of exercise go for torque and the TDZS2. Both kits are suitable for a 68mm bottom bracket, so just check that first. But Pashley recommends mid drives on their website, so it’s probably fine.

 

If you are unsure which one you want then call them and they will advise you of which one would best suit your riding style.

 

Also they will help you choose the best battery configuration for your bike if you send them a photograph.

I don't want it to be road legal, I want to unlock it.

Then go for a BBSHD. I bought mine from here:

 

https://custombuilt-ebikes.co.uk/

 

But be aware that this motor is very powerful and you really have to be mindful of your braking performance. Also you have to consider the torque it will impose on your transmission. It produces 160 NM of torque that goes straight through your drivetrain. That’s twice the amount of torque that the BBS01 produces and the BBS01 is no slouch.

 

I fitted a BBSHD to my MTB, went for a test ride, came back and ordered a set of 4 pot hydraulic brakes before venturing out on it again.

Can I add dynamo front hub for lights?

BBSHD comes with a lights output and mine even came with a free front light. All you have to do is press the up button for a couple of seconds and the display back light comes on together with the headlight.

Usually twist grips for eg gears rotate on the part away from the edges of the handlebars, and the end part of the grip is fixed rigid to the handlebar. I'd guess the same would be true of most twist throttles. but maybe not. If it is it's that fixed grip part that needs the end cut to access the hold at the bar end.

My MTB currently has a DWG22C rear hub motor. The plan is to transplant the wheel into a Pashley Mailstar.

 

The design changed, but many of those Pashleys have derraileur hangers. Mine will be respaced to 135mm for the hub wheel. It handles better with weight over the front wheel, so the battery is going where the basket was. I'm going to braze cantilever mounts onto a plate which I'll bolt into the rear triangle so it can have a magura brake over the chainstays.

 

Undecided whether to stick with the Sturmey drum up front or not or fit a disc fork.

 

While I'm not your mum, I think it would be foolish to try to make a bike like this too fast. 15.5mph is plenty for this sort of bike.

 

They are a brilliant candidate for hauling your shopping about and stop-start journeys but will be very unstable at high speeds.

Oh, and the reason I didn't buy a mid drive even though this was the bike I was going for is I thought it would sit very low. I reckon you could bash it on a kerb.

How long do Sturmey Archer XR3-D 3-speed gears last with a Bafabg BBSHD? Can you get to the end of the road or do a complete ride before they explode, or is it even longer? Asking for a friend.

I could change the brakes to hydraulic so that removes that problem.

It definitely will but you could probably eliminate that with larger tires

id not recommend a hd on that sort of frame esp if you are planing to use full power mode cos that thing will be going 40mph+ with the right gearing.

 

my m8s bike has broken 2 seat rails and one of them was made of titanium.

There is not loads of clearance if you want to keep those mudguards.

The braking is only one part of the issue. Hit a pothole at 20mph in one of those, and see what happens.

 

There are much better bikes to do a conversion on, honestly. I would much rather have an MTB with a suspension fork for this.

You can tow a bike trailer using pretty much any ebike conversion of your choosing - far more capable a solution for hauling cargo IMHO.
