I am looking for a light but speedy folding bike. I am 6'2" and 210lbs.

The JAVA "Fit" caught my eye on ebay

Anyone had experience of this bike or do you have recommendations on any other bike?

Many thanks

Smaller wheels are generally stronger than larger ones. However the bike in question looks like it has fewer spokes than i think you might need. Just an observation, at 210lbs. id be looking for sturdier wheels(more spokes). Alot of folder weight limits are only around the 230lbs. for rider. Your also pretty much at the limit for most folders in height,i didnt see a listing for how tall a person can fit it. Although i guess mods can be made usually.So maybe look around a bit more.
Lets see what others have to say though.

That looks like a rebranded Hasa. Hasa bikes are rare in the West AFAIK, and there are no reviews here AFAIK, but they are popular in the Far East.

I think the number of spokes would be OK as long as they are properly tensioned.

You sure you'll have enough seatpost extension? (didnt see that spec) Often the problem for taller people.
