Three Bike Comparison using Accelerometers

Comparison of three bikes - a rigid bike (no suspension), a full suspension bike and the interconnected suspension bike over a 70mm speedbump at using accelerometers on the frames. This is to demonstrate the significant reduction in shock transmission afforded by the interconnected suspension which allows the bike to be ridden faster and with less fatigue over bumpy ground.


Three Bike Comparison Slow Motion Replays

This is a comparison of three bikes, a rigid (no suspension) bike, a full suspension bike and a prototype interconnected suspension bike over a 70mm speedbump at approximately 25 kph. The high speed film clips clearly show the response of the bikes to hitting the speedbump - in particular the time that the front tyre is airborne (causing loss of steering control) and the disruption to pedalling caused by the rider being "kicked" off the saddle. The interconnected bike shows some clear advantages.


Three Bike Comparison Rough Track

This two minute movie contrasts the performance of three bikes (rigid / no suspension Vs full suspension Vs interconnected suspension) over the same, typical piece of Warwickshire canal tow path. In each case the camera was mounted to the frame just beneath the saddle, showing the movement of the front forks. The three clips show the progression from the rigid bike (which was barely in control) to the prototype interconnected bike (which was relatively unchallenged by the surface). What isn't shown in the movie is the progression of the rider's vision line from a few metres in front of the front wheel (rigid bike) to some way in the distance (interconnected bike) - indicative of the ability of the latter to negotiate all but the biggest undulations without any problems.
