Spring-powered wheel claims to be ‘E-bike different at decrease price’

An Eire-based entrepreneur is claiming to have invented a power-assisted bicycle wheel that doesn’t use batteries, doesn’t want charging, shouldn’t be pace restricted and has an infinite vary.

Simon Chan says his SuperWheel, which is powered just by weight and motion by way of a patented know-how known as ‘Weight to power conversion know-how’ (WTECT), provides an effectivity enchancment of over 30 per cent in comparison with a regular wheel.

Based on SuperWheel: “The WTECT system is a sort of suspension system, utilizing the reactive pressure to generate further torque, to facilitate the wheel rotation.”

It contains two mechanisms: the exterior spring mechanism and the inner drive: “The motion/response pressure brought on by weight compresses the springs within the higher part of the wheel and decompresses within the decrease part. Utilizing the centre because the pivot, this converts power and reduces the frictional pressure in the other way and facilitates the rotation. Utilizing 10kg energetic weight, the mechanism is proven to generate a second starting from 7.3Nm to 7.8Nm.”

Chan, who already has a distribution contract with a French firm, the place the primary manufacturing models have reportedly gone on sale, is asking the SuperWheel an “E-bike different at decrease price.”

Chan says the SuperWheel’s journey started in 2014 and by 2016 had accomplished computerised valuations and digital prototyping at Dublin Metropolis College.

Based on the Technological Greater Training Affiliation (THEA), Chan acquired Enterprise Eire Innovation Voucher funding to assist his work on prototype improvement, plus further assist from Dundalk Institute of Expertise – the place Chan’s firm is now primarily based.

THEA says the SuperWheel is being marketed to “metropolis commuters, biking fanatics, to any environmentalists on the market nonetheless utilizing much less sustainable transports and to individuals who could have a mobility drawback that restricts them from biking. Utilizing the Tremendous Wheel is a inexperienced and environment friendly mode of transport.”

The SuperWheel will likely be suitable with most traditional bikes, with totally different wheel sizes deliberate, from 20in to 700C. It’s accessible to pre-order by way of the SuperWheel web site at €395, however is at the moment offered out.

We have now requested a SuperWheel to check and can report again.
