The bike ramp was delivered efficiently and seemed an attractive product. But with a heavy Yamaha MT10 on it on a paddock stand it was alarmingly unstable for the first few inches of lift, and though less so when fully up it was still unsafe. The cause was inadequate strut geometry when part way up combined with a lot of weight through paddock stand wheels at the rear, a long way from supporting struts. In fairness, though the width suggested a paddock stand could be used, this was not claimed. With the MT10 on its side stand, the stand and wheels had to be placed very carefully. If the stand were too far to the left (with wheels central), the whole ramp distorted badly enough to almost lift the rear wheel off the deck. I have made side supports to give much needed security (see image). Also the wheel clamp is strictly suitable only for upright bikes on centre stands. If used with a side stand it would need new holes drilling for position in accord with above.
That's my experience, but maybe its better with lighter bikes.
