I put a Luna cycle suspension fork on my ebike uses oil and air so it is adjustable have to buy special pump to put air in forks slightly raised front of bike
Just put a Luna lander fork on my fat tire bike works great can not feel bumps or cracks any more. Ride mostly commuting, makes the bike taller and longer.
All I saw at the expo were expensive european style pedal assist bikes with 250 to 350 watt motors which go 15 mph. It was like they were embarrassed to enjoy 3000 watts with a throttle. The best thing I saw was a Z bike in the parking lot.
