I think I would be safer peddling, or at least be able to go up a hill
If your referring to the rather weak 250 Watt motor, you should keep in mind the fact this is likely designed for a European market where strict limits on electrical assist bikes are in place. Here in the UK for example, we are only allowed a
200W motor on a bike, and a 250W motor on a trike / quad. Our speed is also set-in-stone at 15MPH. A bigger motor, or a faster speed, and you have to register the bike / trike as a "moped", have a vehicle approval test, MOT and Insurance - but at least the road tax would be free as it's electric...
