July 2017| 29 announced a new , cell battery. These batteries are touted to last longer, have a bigger capacity, and let you cover more pedal-assisted ground when fitted. This all happened because Tesla wanted to create a budget version of their electric cars, helping to push technology to the benefit of cycling. When will you see a , -cell battery on an e-bike They look highly likely to be a part of many brand s models for the season. The battery will be slightly bigger than the current 18,650 but the improvements will more than make up for that. The , battery is 18mm in diameter and 65mm long, while the new 21,700 will be 21mm in diameter and 70mm long. It is not a huge increase in si e, but the output is. The current , batteries are managing 3.5Ah and the new 21,700 will manage . Ah. The life of the battery is also hugely increased and part of this is due to the increased output. This means that you should not need to charge your battery as often, this prolongs its life and you should see this rise from 500 recharging cycles to between 1,500 and 2,000 cycles. greener. The team have already have created a sodium ion-powered e-bike but the timeline on the mass adoption of the technology is as yet unknown. If we pull all this together, we can see that there is a lot coming from the world of e-bikes and to bring us back to motor manufacturers, Ford believes that the folding e-bike is the future of an integrated transport system. Allowing people to jump between cars, trains, buses, and ferries with ease and no hassle, also means that those for whom a conventional bike is of no use can still benefit from cycling. As such, Ford are currently in an experimental phase with where they would like to take e-bike design, but with their budget, it can only be safe to expect big things from one of the top five car manufacturers in the world. It seems that many people with motor trade experience are bringing their ideas to the e-bike world. The other ma or advance is sodium ion battery technology. Lithium ion batteries require lithium in order to be made, a volatile material that is expensive to transport and work with. As a result, any application of lithium is expensive. Scientists in Sheffield have, however, started to develop sodium ion batteries. These are a direct replacement for lithium ion batteries, allowing current li-ion battery manufacturers to use existing equipment to construct batteries using next-generation materials. Sodium ion is cheaper, more abundant and
