This unique unit has been reworked but it is still heavy, bulky and hard to store. It needs levelling carefully too, because any tilt will be amplified by the rubber mounting.
The rubber knobs and quick-release latch do make it very secure, but its two-piece rubber-cushioned frame is very tall, which means Kinetic's rotating riser block (£39.99) is worth getting to complete the kit. We'd also suggest some sort of side step for easier mounting.
What you do get is a ride where your bike can tip and tilt as you power out of the saddle; some testers loved the feel, others found it distracting. The engine is good, with a labour-intensive start but it's smooth and quiet once rolling and has good sustain.
A shallow resistance increase means it's ideal for more subtle extended sessions as well as intervals.
