"FWD is silly and can be dangerous without a strong fork. On a road bike you'd want to convert to a steel fork."
For sure it can and has been done wrong with disastrous consequences but I chalk those up to Darwin nominees. If looked at from a technical standpoint it can actually work quite well.
I've got 3k on this bike primarily on gravel and paved roads with some trail work tossed in when the mood and opportunity strikes.
1000w peak, legal in OR where I reside, but used mainly in 500w mode, as set by my CA/controller interface selectable in 250w increments, for battery preservation purposes and the fact that it also provides enough speed over terrain for my purposes.
Bikes Direct brand carbon fork with carbon dropouts with a torque arm on the disc side. Bike also utilizes regen. I keep an eye on the fork for stress related issues but so far so good. I keep the axle nuts properly torqued.
After going through all the options over the years I find that front hub/throttle/cruise control is my preferred setup for road use. Allows for complete autonomy at the pedals that provides the best feel of the gearing in relation to terrain while the motor helps provides constant momentum nicely making up for my dead spot spin. Hill climbing on gravel is really good with both wheels driving. YMMV of course but I always get a bit tetchy when I see statements like above from people that have only based their experience on what they have read, not what they have ridden.
