Mongoose Malus Fat Tire Mountain Bike

I bought this bike to turn into a commuter ebike. I’m not done putting it together but if I only bought it to ride regular I would have to put more money into it already after only a couple of days. I put it together and riding in the first day was okay but the chain makes a sound every time you pedal with your left foot. Then the second day the left pedal popped off and stripped the hole in the crank arm so now I have to take it to a bike shop. Thought of just welding it on but I’ll see because I mainly will be using throttle using a 72 volt 40ah 3000 watt setup I just needed a bigger tire bike because I’m a bit heavier and bikes with suspension are more expensive but I might return it because it’s such a hassle after not even having it for a week. If you get this bike for off roading I would recommend a new seat like I got because the seat is small and uncomfortable I also thought the frame is solid and lighter than expected but I also thought it might have more give when riding and more bounce flexibility wise but it is smooth off road from what little riding I did on the first day. The transition from smooth road to off-road was almost unnoticeable. If I didn’t have a pedal problem or a chain problem I would give it 5 stars because for the money it can’t be beat even though it’s a little stiff but with my issues the best I can give it is a 3 star and if it’s too expensive to get the pedal and chain repaired in the next week I will be returning it
