I guess everybody is tired of this topic, but I have just joined up and have to have my say.
I am trying to buy a pedelec, but I don't really want to spend 3 or 4 grand on a new Haibike or KTM unless it does everything I need. I want a bike I can pedal on roads and technical offroad tracks, with as much effort as I can comfortably expend, but I don't have the stamina to keep up with my son who can easily average 20mph over 50miles on his road bike on hilly terrain. He is nothing special fitnesswise.
I can personally average 10 or 15 mph over rough hilly tracks for short distances. I can do 20 or 25mph on road for very short distances with no wind and can far exceed this on steep downhills. As I am getting on a bit and have mild asthma and troublesome knees there is no way I can keep this up.
The pedelecs I have tried are great up to 15mph, but if I pedal harder there is a braking effect and whatever I do I cannot pedal on the flat at a speed I would be capable of doing on a real bike. Even allowing for the extra weight, if I could disable the motor completlely for short periods and remove the braking effect I would be happy - why is this not possible?
The speed of 15mph is perfectly acceptable offroad, but not onroad. I think 20mph would be a reasonable assisted speed onroad and on official bike tracks.This is the opposite of what I understand a lot of people are asking for - obviously for organised offroad events or private location there need be no limits.
By the way - so I can cause the usual uproar from the traders here - the UK is being ripped off price wise on ebikes like everything else - the prices in pounds are pretty much the same numbers as they are being sold in Euros in Europe. - Yet another reason for buying over there.
With our narrow bike tracks shared with pedestrians and dogs, speeds of 20 mph would be bloody dangerous I should think. You have to remember that if it's a bike it can use bike facilities. Which in this country are designed by people who think bikes go at not much more than walking pace.
My bike pedals past the cut off quite well on the flat and gives assist up to over 17 mph legally by taking advantage of the ten percent leeway in the regs. There was a thread here a month ago in which people posted the cut out of their own bikes and many were the same as mine.
A good quality crank drive bike with road tyres pumped up to a good pressure should roll fine past the cut off when it's up and going.
