Eurobike Idea bikes: Recycled plastic, hydrogen & hubless

Eurobike has a little bit of all the pieces, however these wild prototype idea bike tasks from Muzzi Cycles, HeFlow & Komo Bike caught our eyes. Muzzi is a one-piece molded plastic body that may be recycled and even comprised of recycled materials. HeFlow is an adaptable 4-wheeled cargo bike powered by a hydrogen engine. And Komo’s mission is a mini-wheeled metropolis ebike with no hubs…

They’re all fairly wild.

Surprisingly sufficient, the completely one-piece plastic Muzzi Cycles body mission has really been round for greater than 20 years, with practical manufacturing as early as 2008.

However within the time since, this made-in-Brazill idea bike has advanced the body design itself, and even the fabric that it’s comprised of.

Environmental sustainability has been been a key focus for the reason that begin. And these newest fashions are created from a mix of varied recycled post-consumer plastics, and now even “photosynthesis-based” frames that incorporate biomass fibers within the injection-molded composite mix.

Because of the modular design – and the thick ensuing body sections – the Muzzi Cycles has been in a position to be tailored to numerous newer requirements lately.

The newest Muzzi mission bikes have tailored to disc brakes (however nonetheless QR axles, to this point) with bolt-on metallic dropout plates.

Muzzi have even managed to show the sustainable modular recycled plastic mission bike into an e-bike now, screwing a battery beneath the plastic downtube and including a front-drive hub motor that allowed them to maintain the common disc brake / derailleur-geared rear finish.

HeFlow H2 hydrogen-powered cargo ebike

A bit additional away from one thing you should buy straight away, the HeFlow 4 H2 is a 4-wheeled cargo ebike platform, powered by a hydrogen gas cell.

The Alpha Neo Hydrogen AXH gas cell packs a 480W PEM gas cell that’s used to ship energy to the 250W electrical drive system for the rear wheels. Output torque is rated at 120Nm to propel this beast, and the gas cell shops an enormous 1300Wh of vitality to provide it an extended 150km vary.

This quad cargo e-bike seems fairly superior… and possibly even trail-ready.

However the actual trick although is that the gas cell could be refilled and recharged to its 300bar (4350psi) max strain in simply 2 minutes making it very best for repeated service the place you gained’t have to attend for a battery to slowly recharge.

The usual 4-wheeled HeFlow cargo ebike weighs 75kg, and might haul a 200kg load.

With 27.5/650b wheels it may be constructed up with city slick or knobby mountain bike tires. The usual utility mannequin has this inbuilt field, however there are additionally a few totally different supply trailer add-ons potential together with one that may haul a full-size pallet, plus a household mannequin with a youngsters seat within the again or a MTB mannequin with a low-profile baggage platform.

Komo Bike hubless ebike

This final one is one other e-mobility engineering train out of South Korea. The Korea Mobilty improvement firm of the hubless Komo Bike appears to only wish to show the viability of the “futuristic design” idea.

The hubless entrance wheel spins round rollers on the quick sprung fork, and involves a cease with a traditional V-brake on the aluminum rim, then wrapped with stable airless Tannus tires.

Komo Bike hubless ebike, rear wheel

The hubless rear wheel is pushed by an enormous rim-sized cog with a direct drive to the motor that acts a regenerative rear wheel brake, as effectively for a claimed 15% increase in vary.

Tucked in between the 2 wheels, the Komo idea bike really makes use of a traditional hub motor, a minimum of on this working prototype. For now all of it sits in a cumbersome, bolted-together aluminum body that makes use of many 3D-printed elements to complete off the futuristic seems.


Komo Bike hubless ebike, view

Whereas the absolutely hubless Komo Bike idea continues to be a methods off… look via that hole rear wheel to see the Komo Sensible, a extra present ebike that swaps in a traditional derailleur drivetrain, spokes, and rear hub motor for practical simplicity. The Komo Sensible nonetheless will get the hubless entrance wheel and is serving as a proof of idea and test-bed for the additional improvement of the fully-hubless mannequin.
