"The European Commission (EC) has today released its proposal to amend the Motor Vehicle Insurance Directive (MID), which would mean that pedelec users without third party liability insurance would be riding illegally." http://www.mbr.co.uk/news/e-bikes-insurance-375828
I didn't say it was a deal breaker and I voted hot, but the battery price/life issue is very real and few buyers are aware of it initially. Replacing batteries on a cheaper ebike is rarely viable from a cost point of view: may be better to remove all the electric stuff and sell on a decent conventional bike.
Depends, if you keep using it until it totally runs out or stick it in the shed for five months and expect no loss in capacity. Also, conversely, it is pretty certain that in 2021 batteries will be cheaper and higher capacity than now. By creating a market for batteries it ensures that they will continue to be produced and the bike will not be obsolete. I'm no fan of electric bikes, i think appropriate gears are much better. However, the battery issue is hardly a deal breaker.
Looks good for the money but the problem with ebikes is that the battery life expectancy is around 3 years and you are then faced with a BIG bill to replace it (usually £300-£500).
Possibly, but adds further weight, of course.
