I can't currently drive my car due to a medical condition. I needed something to get around on (apparently not even supposed to operate a moped but that's stupid florida law for you) and this seemed to be the only option that didn't require any type of operator's permit. Federal law limits this sort of bike to 20 mph maximum speed. I was told that currie makes good Lightweight folding bike, I priced them locally and they were a bit high I thought so I started looking on the net and found amazon's price a lot lower than what others and shops were selling it for. I got the Lightweight folding bike last thursday, it was mostly assembled all I had to do was attach the pedals and the riser off the fork/handlebars and put the front tire on, not much at all but the instructions that come with the bike were not made for a novice, first I couldn't figure out how to release the front brake so I could mount the tire (you pull up on the black metal piece to release it) then I couldn't figure out how to tighten the riser off the fork (you have to open the folding joint and the hex screw is hidden inside there)...the rest wasn't bad. The third problem (same one I have with all bikes) is that I'm only 5 feet tall and the seat was way too high for me even all the way down, every time I stopped I nearly dumped the bike over. The solution to that was to have a fried cut about an inch and a half off the end of the seat tube and then to also loosen the seat screws under the seat and tip the front down a little bit to make it easier to get on; between these two fixes I can now deal with stopping without dumping the bike every time. Before you ride the Lightweight folding bike the first time charge the battery overnight (it says 8 hours but the first charge should be extra long) these are sealed lead acid batteries, heavy as heck and should last about three years of daily use.This is The great valuable Lightweight folding bike
