Hello everyone, and some offroad advice needed.

[20ston]

Hello everyone, my name is Tony and i am new to the forum.
i started using a electric assist bike about 18 months ago, due to a heart problem.
previous to this i had been a life long cyclist.
i bought a kalkhoff pro connect disc, after doing a bit of research. i need a bike that i could do some longish rides on and also tour on. to be honest it has been great.
the longest day i have done on it is 60 miles, as part of a 300mile on/off road tour last september.
i now want to source a bike or conversion kit that can take me 'proper' offroad.
looking for something that can do 30 milesish ride in the lakes/dales/scotland.
i am ok spinning on the flat and downhill, but i need assist for uphill.
i had a talk with a guy about a Haibike enduro full suspension bike, which looked fantastic.
i just do not know anything about the power and range of this bike. or indeed any bike.
i have been told some bikes are set up for distance and some for torque/power.
hopefully someone will be able to shed some light for me and point me in the direction of a bike/conversion kit suitable for my needs.

thanks very much.
