Your wording makes me think that you believe that a front motor kit is free of the need to fabricate torque arms. This is incorrect! Even a steel fork needs torque arms. Two of them. You don't have to fabricate them. They are readily available from wherever you get your motor. All you have to do is attach them. Yuba makes a Mundo with an integral motor. Guess where it is. Yep, mid-drive. Cargo bikes are the poster child for high grunt, stump pulling torque excess and that is where mid-drives shine. The next most popular place is the rear hub, because rear dropouts are stronger, and 500W - 1000W is a handful in a front fork. If it all seems daunting get help installing but don't put a subpar vehicle on the road just to escape some hassle.
