Hello
I want to convert a high spec steel tubed ( Reynolds 753) mtb bike to ebike front hub motor. Does anyone know where I can buy the latest spec bafang motor or anything better? I want to build my own wheel with a high quality rim and spokes. I've searched internet and there only seems to be Amazon or ebay but sellers don't give any info on the motor model numbers just wattage and voltage so you don't know what you are getting.
Regards

All motors are much of a muchness. I wouldn't say that Bafang are not amongst the best.

Before anybody can give advice, you need to tell us about your requirements. How fast, how powerful, wheel size, etc?

Why do yo want a front motor rather than a rear one? What sort of forks do you have? Are they steel too? Are they rigid or sprung?

You don't need a high spec rim and spokes. I think that the cheapest ones are the best.

front hub motors are easiest to fit but can lose traction on wet roads or grave.
I have the XF07 in stock.

Rear hub motors take a little longer to fit because you will have to transfer the cassette or freewheel from the old wheel to the new wheel but give better traction.
I have Aikema 85SX, Bafang SWX02, MXUS XF08C and Shengyi DWG22C rear hub kits in stock too.

Thanks for the reply.
The bike is a 21" all steel Reynolds 753 tubing with Shimano XT groupset with 26" 559 wheelset 100mm OLD. I want to keep the bike as original and light as possible hence going for a front hub which I would lace to a high quality 36 spoke 559 x 1.75 alloy rim which I would hope keep much of the excellent response of the original bike.
Do Whoosh have the spec of their rims and spokes?
Any recommendations?

Hello Multispeed,

if the priority is to keep the bike light, the Aikema 85SX rear hub kit is difficult to beat. It is lightweight (1.9kgs), high torque (40NM), stealthy and quiet.
The XF07 is a little easier to fit but the difference in time is about half an hour, to transfer your old cassette to the new wheel.
I would lace to a high quality 36 spoke 559 x 1.75 alloy rim which I would hope keep much of the excellent response of the original bike.
The 559 rim on the motorwheel is painted black, standard double-walled aluminium 36 hole construct, outer width 30mm inner width 25mm, laced with 13 gauge black spokes.

Yes, that's why I posted. Very good service and lots of choice more so then any other sole store, a few of us I believe use them.

I haven't used them post brexit so can't say what/if any additional charges may be incurred, the std extra charge was a £12 handling fee & an £8 -£10 duty fee.

Thanks again. I can see that converting an eBike is a bit of a minefield in getting all everything coordinated

If you get a complete conversion kit from a good supplier (eg Woosh) that ensures everything is coordinated. You will probably pay a bit more, but get good advice before buying and for fitting, and continuing good support should you need it. You'll also avoid the complications of customs, VAT etc on imports, etc.

Of course, it you have specific requirements their kits don't match then you are back in the minefield. I chose the Woosh route as a novice to keep things as simple as possible. If I needed to fit another kit I'd probably do the same again unless there was a strong extra reason against.

I bought a complete kit for my first conversion and it made things a lot simpler and has been great. A friend bought a complete "cheap and cheerful" kit from Ebay - it's was also very simple to fit but it's been a big disappointment as it's very basic.

I've also done a conversion using parts from different suppliers, not too difficult but you need to be very careful as it's so easy to end up with a parts that won't fit together due to mismatched connectors or incompatible bits.

The cheapest kits have crappy controllers and control systems. They work and are generally reliable, but a decent controller makes the bike much more user-friendly.

When you've never converted a bike, it seems complicated and there are a lot of choices; however, it's only really the battery that costs a lot, so you can swap other parts later if you don't like them unless you're really strapped for cash.
