Hello all

All things considered equal, how would you choose between a 1000w motor and a 1500w motor?

Is greater motor wattage equal to greater top speed and/or torque?

more voltage more amps more speed tho the faster you go the bigger the batt has to be.

thats why a bomber bike is like 60kg ;)

no the last one will have 2 times the range as its 20ah

both will be the same speed.

So a bike with a 60v/10Ah battery is slower than if it had a 60v/20Ah battery?
No, the position is more complex than that. Your original question isn't answerable in that form, it depends on the design brief and motor type among other things.

The 1500 watt can be a little faster and have a little more torque combined, or it could be just faster or just more torquey than in the balanced form of partially gaining torque and speed.

If you specify the type of motor that makes the question a bit more answerable, but the best way to approach this question is to state what your requirements are. Then the best type and spec can be recommended.

My only point of reference is my Cyclamatic CX1 and there are NO bike shops in the area where I can test-ride e-bikes.

My requirements are as follows:
a) ~30mph top speed
b) better torque than the Cyclamatic CX1
c) the greater the range, the better

I ask myself, why should I get a cyclotricity stealth 1000w for 1200 pounds instead of buying:
a) 1000w conversion kit off ebay (~200 pounds)
b) 60v/20ah battery with charger from Aliexpress (~500 pounds)
c) Some random, albeit compatible, bike from Halfords (~200 pounds)
d) Pay someone to put everything together since I can't do it myself

Does this not make sense?

Some form of warranty, because electric bikes do and will go wrong.

If any one of the components in your list goes wrong, you'll have a massive battle trying to claim on the warranty. Even the Halfords bike, once they realise you've fitted a kit.

Cyclotricity:

1 year warranty!

OK, 30 mph is a good start point. If you aim for a hub motor that's specced to achieve 30 mph on a stated voltage, a higher wattage version if there's a choice will give more torque. So that answers your original question in one respect.

Regarding your listed options, since you can't do it yourself, the Cyclotricity Stealth seems the best option in every respect, assuming it can reach your required 30mph.

That's not the point.
The legal bbs01 is fast enough. If your after super thrills then you might as well have the bigger motor.
I disapprove but if your going for it then go all the way.
