The other option is to buy a second hand bikes off Facebook marketplace / Gumtree / eBay and fit (or get someone to fit ) a conversion kit

Thanks @saneagle - that was very interesting, I changed the motor to an XF07 and then a AKM G75 with 20" wheels and used 15A and 18A controllers and played with the gradient and the throttle (current based throttle) and as you say for the same speed, for the same gradient the motor running at...

I think I would stick to one of the suppliers that has been recommended here

Yes - I remember. So if a 36v hub motor has a "no load" max speed of 21 mph (say) and a restricted speed on the flat of 15.5 mph, it is running at 74% of its no load speed, which will usually be around peak efficiency ? If you then use a 48V supply on the same motor then its "no load" max...

There's a couple of variations on that theme. I got mine from Yosepower, but you can get higher capacity ones off Ali express. I got this one : https://www.yosepower.co.uk/products/36v10ah-seat-tube-li-ion-e-bike-battery But they also do a frog battery (you will need 36v)...

I could understand that with a 201 rpm @ 36v hub motor winding compared to a 201 rpm @ 48v hub motor winding, you are getting more power at a lower current, so more efficient. But if you run a 201 rpm @ 36v motor at 48 v with a 26", 700c or 29" wheel and restrict it to 15.5 mph won't it be...

You could do the Woosh conversion with a "seat post" battery, that is lockable and detachable and either install the battery mount on the seat post or on the front as I did here

I don't think there is anything "magical" about them, just the same cells in a different layout. Depends if you are heavy, climbing steep hills or towing or want to go faster. Is there any area you want to improve on your existing conversion ?

I was just thinking that - they look like they are pointing downwards, I can rotate them so they are pointing more towards me (They've been like that for 10 years !)

Boardman 29er Scott Genius (26" wheels) So just tried sitting on both and comparing them side by side The Scott handlebars (surprisingly to me) were slightly higher and slightly curved towards me Because the wheelbase was shorter, the center of the handlebars on the Scott was closer to...

Just did a similar route, 1hr 45 min ride, on two of my bikes, boardman 29er with mid drive and an old scott genius MC40 hub drive with 26" wheels. When I came back, I noticed I was a lot more "achey" after the (much newer) boardman ride, with arms , shoulders and back aching a bit. When I...

Sounds like the battery is good, that's always a worry on second hand purchases. What you need is a dual 36/48 v sine wave KT controller/display/throttle/pas kit, at least 15 amp max, maybe 18 amp max. This will have the cadence sensor and you can set the throttle to behave in a UK legal...

Welcome!

Yep, as @saneagle mentioned, the display showing the motor getting 500 watts (or more) is perfectly normal for a legal e-bike - it's the manufacturer's motor continuous rated power that counts. Again most legal e-bikes have settings that limit the maximum speed to 25 km/h, as long as this is...

So finished now, motor fitted in without needing any washers. Not sure with the wider MTB bottom bracket that there would have been room for the locknut if a washer was needed. Had to use a rear rack battery not enough space on the downtube. 250w rated TSDZ8 motor from @Woosh Marathon 365...

Can probably get cheaper from Chinese sellers but if you want to buy all from one place with the Woosh support https://wooshbikes.co.uk/cart/#/product/uid-251-dwg22c-48v15ahr/dwg22c-rear-hub-48v-250w-kit-with-48v-15ah-rack-battery

Short answer, I think it will be fine. Slightly longer answer, the Yosepower kits used AKM geared hub motors, the "350 w" motor has a higher top rpm (and hence worse hill climbing ability) than the "250 w" motor. The manufacturer just used 250w and 350w as a proxy for the top speed, in...
