It looks like a cross between a Meccano set and an Ikea lampshade, but the Trayser is, in fact, the latest e-bike from New Zealand firm ETT. It is certainly eye-catching, but all the design flourishes also conceal a remarkably forward-thinking bike. The plastic wraparound shell hides a 42V lithium ion battery which gives a range of 60 miles at up to 15.5mph. It takes 300 minutes to fully charge. To ride, it’s wonderfully comfortable and the electric pedal boost is instant and responsive. But where the Trayser really steals a march on the oppo is that it is the first bike for which you can 3D-print replacement parts. Simply visit shapeways.com, and click and order. If you are feeling imaginative you can even 3D-print your own accessories and build your own unique creation (ettindustries.com).
