I had a chance to test drive the S20 today. Here are my findings:
(Disclaimer : I currently ride a Nik+, never rode a wheel with suspension. Total EUC experience = 10.000km)
It is a really beautiful and impressive looking wheel
This thing is large and heavy. Steers like a large truck. Turning on the spot seems almost impossible. The engine is still powerful enough to give enough torque so accelerating is still quite good.
The wheel is wide, but not so that it is cumbersome.
Pedals are high !
I love the pads ! I really like the pads - so much that when I hopped back onto my Nik+, I immediately missed them.
The handle sucks. I'm 6 ft tall, it is way too low to steer it comfortably, and combined with the heavy weight makes it difficult to maneuver.
I really like the giant spiked pedals
conclusion : quite disappointed with the heavy steering feeling, I was looking to replace my Nik end this year with an S20, seems I'll hold on to my current wheel for another year or so...
