Some bicycles are built primarily for practicality, while others are more focused on novel looks. [Make It Extreme]’s latest project, the extending bicycle, falls squarely in the latter category.
Built around four custom-machined pneumatic pistons, this electric bike can lift the rider about a meter into the air with the flick of a switch. The front pair forms the bicycle’s forks, while the rear pair is mounted between the frame and swingarm. A small onboard compressor is used to charge a pair of modified fire extinguishers, which feed the pistons via pneumatic valves mounted on the handlebars. The wheels and brakes were scavenged from an old scooter. Since the length between the crankset and rear wheel never changes, there is no need to struggle with chain tensioners as the ride height changes.
While we would hate to face-plant from that height, it certainly looks like a fun ride and conversation starter. This is the case for many of [Make It Extreme]’s projects, like a ridable tank track and monowheel motorcycle.
A 36 minute Wordless Workshop is four times too much. But the result is outstanding :-)
Best of all it’s on Make It Extreme’s “Shorts” channel :D
These again? yeah!
Colin is too late to jump in here and claim “Furze Post”.
I understood that reference.

Fun, but far from street legal. Please don’t kill yourself trying to ride these on city streets.
“…far from street legal” based on what law(s) in particular?
The e-bike conversion at the end of the video wouldn’t be road-legal where I am, but those rules vary by jurisdiction. Besides that I can’t think of any obvious legal issues with the modifications.
(I’m not saying it’s a good idea to ride on the roads, of course!)
Elastomania already had it ;p
What about rigging it to project purple (or green, etc) light on the pavement below? And or add a thumping stereo…
It is not legal to ride a bike on the pavement if you are over 7 years old.
Although most people have forgotten about this law including the council that like to put cycle tracks on pavements.
Please keep to the roads or a field.
