There's no mention of a BMS on the lithium battery pack. Without a BMS you run a very likely risk of frying the batteries the first time you run them down to near zero or leave them on the charger too long, or over draw the current from the pack while riding.
There is also no mention of whether that kit is a brushless or brushed motor. Brushed motors with wear out faster and are less efficient than brushless.
No mention of whether the motor is geared or direct drive. The size of the hub in that picture looks to be geared motor. Either way is fine but a 250W geared motor MAY have more torque for hill climbing.
250W is very small motor. You'll be working it pretty hard if you don't pedal it as an e-bike.
Any bike left out in the weather is not going to last very long. Add electronics and the chance of failure goes even higher. Keep that in mind.
If you do not want to pedal, an electric bike really isn't the way you want to go. What you are asking for is a scooter. Electric bikes are specifically designed to pedal along with and none of the electric bike kits are DESIGNED to pull you up a hill without pedaling. Electric bikes are classified as bicycles or electric-assist bicycles and not scooters for that reason.
Other than that, that's a VERY surprising price and a little suspicious. You need to find who the original manufacturer of the kit is to make a better judgement. Heck of a deal if it IS true.
