NIEŁACZNY MICHAŁportfolio

designed rollers only visually differs from the usual rollers offered on the market.

my innovation are hidden modules inthe frame and rollers allowing producing,

storing and taking energy away.

POWER ROLLERSproject developed in the framework of academy of prototyping and fabrication (fablab łódź / ABB).

just a few photos of the production stages and the final product.

useful in repairing fixed gear on the road.

TRACK TIME TRIAL CHAINRING

MESSENGER GUARD bike mudguard made of polycarbonate. finished with rubber liner.

mounted without any additional holders. plotter cut, heat formed, self-supporting, invisible.

RETRO DIRECT DRIVE two gears derailleur, without shifter. cranks rotations way, sets the gear.

RETRO DIRECT DRIVE - CHAIN TENSIONERlaser cut out of stainless steel. profiled in order to improve chain leading.

the resistance comes from the ductile deformation of the tire. welded frame, laser cut out of stainless steel.

designed to provide change wheel or cog without disconnecting the chain. mounted on the wheel axle.

ball bearing pressure roller controlled by bolts.

RESISTANCE TRAINER

the concept of a "pendulum" - a disc with adjustableunbalance driven magnetically.
