That seems about right / a little fast to me - no load speed of 374 rpm at 36V with a 700c wheel. If you wanted to travel at 35 km/h , for a 700c wheel, I think would be around 260 rpm, so for optimum efficiency no load speed of around 340 rpm Presumably you weren't going to use a 48V battery -...

Can you show us a photo ? It's not this one is it ? https://www.amazon.co.uk/Agatige-Electric-Display-Waterproof-Controller/dp/B0BZRFNBPZ

I think it would be technically possible, but not with the Mahle X20 - I think that technology is proprietary and locked. But it would be technically possible to start off with a road bike , add a very lightweight hub motor and add a bag battery and then set the motor assist cut off speed...

I would also be interested in the "no load" speed (with the motor wheel lifted off the ground). I suspect this might be too high for strong hill climbing although the controller shunt mod will definitely help

Took a screenshot and used the Google photo editing wizardry, it's very faint on the listing :-)

On the Amazon listing the OP linked to the sticker on it said current 11a limiting 13a

It's not mid drive, but it does have a 20 amp controller and a heavy duty motor for climbing hills and good battery capacity. Depends what you are using it for, it's ideal for roads, light trails and tracks, not good for heavy duty mountain bike centre "black runs"...

I wondered if the fact that this is a 24v motor with a 36v battery would make the *no load" speed 50% higher, so at low speeds it would take this motor out of its efficient operating zone. I wondered as you approached the level 1 and 2 limit speeds, does a speed controller reduce the voltage or...

Just had a look on street view, doesn't look that steep. I think it's worth trying it on Level 1 or 2, please let us know the results

The only things I can think are the controller isn't supplying enough power or the motor is running too slow so is not in its efficient speed range and not outputting enough power. Shunt mod (search this forum) would be worth a try...

Does the controller specify a maximum current ?

1)What is the maximum current supplied by the controller ? Depending on your weight and how steep the hill then 36v 15 amps or 18 amps should give you a good amount of assist. Wondering whether a slower(201 max rpm) hub motor would be better for you

I think these are the GT 365 with Dualguard rather than Greenguard https://www.schwalbe.com/en/blog/news/innovation/schwalbe-protection-benchmark-of-puncture-protection/?srsltid=AfmBOor4kJxuJ-uydffoq22Ugt06c2HYgsxrUJW2TzX6PFarof7LILis...

Just got some Schwalbe Marathon GT 365 (supposed to be all season, on & off road with puncture protection) 20*2.15 for the Carrera intercity disc 8 that I am converting for my son https://www.ebay.co.uk/itm/355362744973

I think a seat post mounted battery would be ok when you were riding it, it is just below your centre of gravity. Not so good for pushing it about and putting it away. Would a downtube mounting be possible ? If not then rear rack as low as possible and as far forward as possible. There are...

Off on a slight tangent - but when I was test riding the bike for my mother in law (who is a lot lighter than me), I was really subjectively impressed how powerful the tiny AKM-75 motor was, given that it has relatively lowly torque claims. I tried comparing it on the Grin motor simulator to a...
