Yep, the QS really as a lot of "unsprung" mass... :roll:
I think I give the bike a try as it is on 19" front and rear and later maybe have it re-laced to 24"DH and 18"MX here in Germany.
Possibly downgrading to a lighter motor.

I own the 19” 273 pictured with the radial spokes. I have put a lot of amps through that wheel. This motor/wheel combo is great for roll on acceleration runs and seems to hold up well after approx 1000km of hard riding. Putting over 200 amps through and the motor is warm after a 7-10km ride. I don’t find the handling on small jumps and very rough dirt trails great with this motor because it’s heavy. Most people you ask to pick the back of the bike up and can’t lift it. It’s deceivingly heavy. Great for road And just day day light trails. I suspect the radial lacing could be a problem in very rough terrain and off road

200Amps for 10k? :twisted: What is the weight of your bike?

I tried in vain with CNebikes and evelbike.
they said they cannot offer the big motors with cross patterns. I also tried pushing them to do 3x or 4x on their front wheel... nope. seems I am the only one asking them
Custom build a wheel if you feel fruity enough I give it a go and done a 16-1.60 moped rim to a 36h disc front hub with a 3 cross pattern the spokes where expensive mind £70 for the set but they where custom made for me two sightly differing length 12gauge spokes with 6.4mm nipple heads opened the flange holes out on the hub from 2.5mm to 3.0mm and all went together decent.

I laced my hub motor too with a 1 cross pattern I used a 16-2.15 moped rim and 9 gauge spokes little bit more tricky to true I had to build a truing rig but other than that same as front but heavier.

Front wheel weighs 1.35kg no tyre rear weighs 11kg if I can remember correct but these moped rims and tyres dint play nice I've spent £70 on tyres that will not fit I had to go back to 20 inch far bike tyres luckily the extra girth off the wider than bmx style rim gives them a nice seated area to support the side wall so it's not bouncy castle time.
