I'm looking at getting a folding bike for a multimodal commute. I live in the northern suburbs of NYC but will be moving to the city in September. My job is up here so I'll be making a reverse commute. I'll be taking the commuter rail outbound in the morning to the closest station to the office and will then need to get from the station to work... about 4.5 miles. The issue is that the trip there is almost all uphill. If I get a folding bike, it has to be able to handle out of the saddle climbing. I'm looking at the Downtube bikes and they look real nice, but I'm concerned about how the suspension would affect climbing ability. I'm spoiled by my Cannondale road bike... it climbs like a mountain goat. Is this anything to worry about?
