I am thinking of taking my 9 and 7 year old on NYC 5 BBC bike tour (42 miles, mostly flat) on a 24 inch and 20 inch BMX bike.
They have done 23 miles on Princeton freewheeler tour (a few hills) last year on a 20" and 16" kid bike. My wife think the younger one may not complete and ask me to reconsider. What does you guys think? I have started taking them on 10 mile ride (MTB easy trail) weekend and plan to increase the milleage to 20 soon (on paved bike path).
What do you guys think? It usually takes me 2-3 weeks to get fit to ride 50 miles (B/B+ pace) every season (on a road bike).
