The KS18 is a great wheel. Its longer case takes a little getting use to, but is very stable and absorbs bumps in the road nicely. I purchased the biggest battery and I can say that this thing goes forever. At 6’3″, I’m still not getting the hang of the seated ride,but my children have no problem at all riding on the seat. For an 18 in. wheel, the pedal hardness is outstanding. It is very responsive at accelerating and breaking. It climbs hills very well. The automating headlights and break lights are a key feature. Speakers are a great feature as well. If you take longer rides, I highly recommend this wheel. Jason at ewheels is the best. I have no reason to shop anywhere else. I will be buying more wheels from him.
