Thank,s Kirstins but i think other members have changed there tyre on there e bikes and have seen a great improvement in performance so hoping to here from some of them as to what is the best tyre,s to fit.
Sure, I'll try to a little clearer. so Yes, your rims should take 1.5 as generally MTB rims will take 1.5 to 2.1
As regards "great improvement in performance" - what exactly do you mean ? better grip, better rolling resistance, better puncture resistance, better absorption of bumps (i.e increased comfort) ?
I'm not trying to be difficult but its just these things are a trade off !
I get the impression - please let me know if I'm wrong - that you are seeking faster tires ie. less rolling resistance, less weight but with some puncture resistance. IF thats the case you've got a trade off decision to make right there
By reducing the tire volume and increasing the pressure you'll get a faster tire. But it will be less comfortable and less absorbing of bumps. At the same time reducing the amount of rubber in the tire and removing puncture resistance also makes them lighter and faster. But they you run a risk of punctures. The Conti Travel contacts that I recommended are puncture resistant and take high pressures. They are fast rolling - have a slick centre with tread on the edges for cornering. I think they are a nice blend of light, puntucre resistant, grip and fast for road going ebikes (with the occasional bit of light trail)
Does this help at all ?
