My first week riding EEZZ D3 was great. The bike seems like it was made for me. Being short helps and having hills to climb also but I must say for a tall person on flat roads this is not for you. The gears are too low for flat rides and I'm not sure who designed a bike like this but if you live in a hilly area it works. What I have noticed is you need to lean into a turn because of the short wheelbase and small wheels. It's like riding a scooter where you lean and turn the handlebar at the same time. I'm getting used to the handling but there is a learning curve to ride this bike. Also there's a learning curve to the fold and you need to pay attention as you fold it in. The unfolding is easy and no problem but if you're interested in a quick fold look elsewhere. Sure you can fold it fast but take the chance of doing damage to the frame and fork. I bought it because I need to carry the bike up and down stairs and it's super lite. I own a 2 speed Ti Brompton but this feels lighter in weight or the same . Some of my work areas I can not take the bike inside and didn't want to leave the Brompton outside . At the new pricing of these bikes it is a good deal. I can recommend this bike to anyone looking for a lite weight folding bike who is not too tall. I'm not sure if the gearing can be changed but I think not. If higher gear ratio is your thing then look to the Curve i3 . I hope this helps anyone thinking of purchasing this bike .
