Eurobike 2012: Bionicon

by 5

Whether you ‘get’ Bionicon or not, it always has some good stuff to see at Eurobike. This year it showed a couple of ‘nearly ready to sell’ concepts that had people talking.

The first is a truly integrated dropper post. Instead of the dropper seatpost going in the seat tube, the seat tube is actually used as the outer of the dropper post. Obviously you’ll need a special frame, but it’s the kind of thing that might appear in some Bionicons in the future and that they might license out to other companies.

Post up...
Post down...



The control cable enters the front of the seat tube.

The post is cable operated and uses a mechanical three position system that offers fully up, 30mm down and fully down. This is 150mm or 6in. As the seat tube is already there, the post weight can be kept light and the target weight is 300g



And now we’ll move on to the E-Ram system. This is something Bionicon has developed and that looks pretty ready to go. The idea of it is a 250W electric pedal-assist system mounted around a standard BB shell. It’s not designed to zip you around everywhere, but more as a ‘climbing aid’ to help with those long climbs and deliver you to the top with enough energy to enjoy the descent.

The batteries live in a special rucksack

The E-Ram motor weights a kilo and the batteries weigh 2kg. The system is designed to be retrofittable to any bike with ISCG tabs.


The production one should have a slightly lower Q-factor


A thick cable and military connector joins the motor to the batteries in the rucksack. 2kg of batteries should give an hour of climbing aid.

Chipps wasn’t around for the dawn of mountain biking in the UK, but he likes to claim that he arrived in time for second breakfast (about the time he shows up for work, then…) starting in the bike trade in 1990 and becoming a full time mountain bike journalist at the start of 1994. Over the subsequent quarter century, he has seen mountain bike culture flourish and diversify and bike technology go from rigid steel frames to fully suspended carbon fibre (and sometimes back to rigid steel as well.)

His riding style is best described as ‘medium, wheels on the ground, trail riding’ though he’s been spotted doing everything from endurance downhill racing to 24 hour cross country racing. He favours mid-travel trail bikes and claims to be wheel-size, gear, brake and tyre agnostic. In fact, his garage spans most bicycle flavours, taking in steel hardtails, carbon trail bikes, even a mountain bike tandem, along with road, touring and gravel/cyclocross bikes.

While he’s happy to chat about bikes all day, his real interest is in the people and places that bikes can introduce you to and he talks as fondly about the trails he’s ridden and riders he’s met as the bikes that took him there.

    That is a tidy dropper solution.
    I assume that you can set it to the correct height then drop it from there?

    Good effort. Hope they do well. Great to see innovation. electric assist looks better than my Sinclair. Assist is not for many folk, but for some it could be great. Look forward to the test rides.

    I love to see stuff like this. More!

    Liking the thinking on the electric assistance….

    I second @AlexSimon – more please!
