I would welcome advice on a specification for a bike for fitness and recreation with grandchildren. The bike will be used on largely off-road terrain such as local cross country ski trails and logging roads, with relatively gentle hills, for a 63 year old grandfather, whose last bike was a 3 speed road bike some 45 years ago. I am quite confused by the modern technology and conflicting advice from LBS, so would appreciate your input to help select a suitable bike.
I assume an entry level hybrid or comfort design will fit the bill but most designs seem to be for commuting/ bike path use. Would I be better looking at a hard-tail MTB design, and even with no suspension?
Should I go for 26 inch or 700 tires, disc or caliper brakes?
Which Trek bike comes closest to your recommendation (From that I can determine competing brand equivalents)?
