Objects in Motion

About

Objects in Motion was Pearson's third titanium bike, following Just Killing Time and I'll Get Me Coat, and the first to bring disc brakes to the material. It took its name from Newton's first law.

It was sold in two liveries: Grey, and the Blue Camo drawn by designer Richard Hall as a nod to the artwork of our Inside Out mental wellbeing rides.

A note for owners. The geometry published for this model on third party databases is wrong, and has been for years. The chart below is ours, taken from our own drawings.

Our premium road machine, this newly updated edition offers exceptional comfort and superb performance however long (or short) the ride. It's hard to overstate titanium's remarkable qualities. Roughly twice the strength of aluminium, titanium is half the weight of steel and handles with the ease of carbon.

We've moved away from the classic 'Ti' look in favour of more subtle graphics, designed to reveal something of the material beneath. The handiwork of designer Richard Hall, our 'urban camo' is a nod to the artwork associated with our mental wellbeing 'Inside Out' charity rides, providing occasional glimpses of the base titanium material.

All Pearson's titanium bikes are made using hand-drawn 3AL titanium for the main three tubes. The highest quality titanium available, it is triple butted to ensure strength and agility when riding.
