I've done two front drive ebikes. First one was a 20" minivello. Rode it several years with an alloy fork. Small Q100H motor. It had 13:1 gearing and with the 20" rims, very good torque. Occasionally, I'd feel the front wheel slip going up hills with wet surfaces. Being a man that worries too much about his bikes exploding, I now have a steel fork.

The second front drive is a 26" cruiser bike with a steel fork. It was only a rim brake fork, so I fabbed a torque arm that held the motor and disk calipers on one side and a torque arm on the other,. Shouldn't explode. The bafang motor axles allowed the use of a torque wrench so I set the nuts to 25 ft-lbs. To my surprise, I found that what felt tight on my other hub motors was only around 20 ft-lbs. Now I use a torque wrench on all of them, employing an open end crows foot wrench if the nut has a cable thru it, With the bigger wheel, traction issues only if starting out on wet leaves. Hardly ever on road.

Still, I'll advise new DYI types to go with rear drive, even though many of us have done front rive, and some have done it with suspension forks, Not knowing a strangers mechanical aptitude and sense for safety. it's just better to avoid FWD..
