We had a lovely day for cycling, the bikes were great. The staff were lovely, I had forgotten my voucher but they were happy to accept my i.d. as confirmation of booking. i would highly recommend this deal.
everything went smoothly - four hours is just enough, actually next time I'll go for a whole day. Anything less than four hours is not enough, time sure flies!
Cycling is without doubt the best way to see Central Park. Rental facility is a couple of blocks from the park, but it will only take 5 mins to push the bikes there (or ride them on the road of you are feeling brave!). Geat bikes, well maintained. Things to bear in mind; some of the trackways in CP are shared with taxis, so you need to take care if you have kids on bikes. Also, some of CP is quite hilly, so fine if you are fit, but if not prepare for some pusing up the steep bits (at the north of the park).
