It could be; bear in mind that it's the size of a 750 and weighs about 3kg (I think I weighed them at Barnsley and they were 3.6kg) so it's almost a quarter of the max weight limit and quite large, but if you can fit it into your design then it should be pretty good. It's only 12V remember - comparing to the 350W scooter motors that are 24V - so if you run at a higher voltage, like 18V, you'll get more than 400W out of it.
