If there used to be one thing you could guarantee to see at Eurobike, it would be that somewhere in the vast expanse of the Friedrichshafen exhibition halls there would be at least one slightly bonkers concept bike, but the last few years have been oddly quiet on that front. Maybe everyone is too busy sticking disc brakes on their road bikes? BMC are bringing back the trend for futuristic concept bikes, with this mighty fine creation.
Is it a vision of the future? Is it how bikes might look if the UCI didn’t have such strict rules? Possibly one or both, or maybe the designers just had a bit too much spare time on their hands.
The bike was created in BMC’s Impec advanced research and development lab. Impec is the unique manufacturing process they’ve pioneered using robots, but haven’t really perfected enough for mass manufacturing of frames. So instead they’ve put it to use making this concept.
BMC weren’t giving many details away about the bike, leaving us to ponder what it might be. Aerodynamics have shaped most of the bike, especially the svelte one-piece integrated handlebar and stem with their own design brake levers and shifters. A computer head unit sits flush in the top of the handlebar and presumably controls the motor inside the frame.
The frame features a neatly concealed drivetrain and judging by that bulge around the bottom bracket it does look like it’s packing an electronic motor and battery. It’s disc-equipped too, which has allowed the designers to chop off half the fork and rear triangle and save a load of weight. Mad it looks, but this isn’t the first time we’ve seen bicycle designers flirt with the idea of one-legged forks and a frame chopped in half.
Highly unlikely as it is to make it into production, it is conceivable that some of the ideas in this concept could be seen in future BMC road bikes in the future. Here’s hoping anyway.

1. You can in principle use any kind of brake with cantilevered wheels.
2. Single-sided forks and stays will in principle be heavier than double-sided ones. Any advantages lie elsewhere.
True - although it's easier to work with brake systems near the hub and fixed end.
Not necessarily, can do but depends on a bunch of stuff not least what loads you expect on the axle and what axle size. Clearly you'd want wider and thinner support structures to avoid pivoting too easily, but wider doesn't always mean heavier - witness frame tube technology over the years.
Reminds me of the "Stealth" technology designed to evade radar
Me thinks the designer has watched 'Tron' to many times
So, in the post apocalyptic/end of fosil fuel world StreetHawk will be on a push bike?
If it's so futuristic, why does it look so 80's?
It would seem odd having motor assistance on a 'sporty' bike.
I've always thought that shaft-drive bikes were an underexplored idea. With a bike frame like that you could very easily have a gearbox at the BB end, a shaft running down the "chainstay" and Roberto's your Italian uncle.
My understanding is shaft drive is inefficient compared to the traditional bike chain which is ok for a motorbike but not for pedal power.
Maybe the UCI should mandate all pro bikes must use gearbox/shaftdrive configuration and drive change in new directions and freeing the rest of us from cleaning chains!
The photo looks like it has a chaincase. Your bike would already be free of chain cleaning if you put one of those on.
progress!
100 years separate these.
@andyspaceman my exact taughts when a saw this where internal bb gearbox as well.
Internal gear box like efneo.com or vyro.com unit with a belt drive possibly. Would be a great step forward for race bikes but the tech is still a fair way off in terms of component weight and gearing options. Removes alot of the the maintenance requirement of a standard drive train.
It's very...'angular'.
Could be, but an electronic motor feels incongruous on a bike like this to me. My money would be on an internal bb-mounted gearbox.
