If anyone is tempted by the idea, I strongly recommend giving it a try. Ms. Liz Ormond's opinion on e-bikes Mr. Spence's enthusiastic praise for e-bikes omits any reference to pedestrians. There is no mention that they are more dangerous than other bikes. Can he tell us what 19 OC DE BESLOT ACAI BESI TE OF 0.8. safety studies have been done in relation to pedestrians, particularly in shared space, and what discussions have been held with organisations such as the Royal National Institute of Blind People?
