Input:
Question: A reviewer indicated the brake was faulty, unless I misunderstood. Has anyone else had brake issues? I am a 4' 10" senior and need stability.
Document: I don't consider that a flaw in the bike; it's just my preference. If you don't have tools you will need them so buy some cheapies somewhere.
This is a very fun bike and I do not have to worry about falling over as I am a senior citizen
However, for the price and need, it does work fine.
I love the bicycle. I felt like there were too many dents. Better packing should be done. Otherwise, everything else was great. It is the perfect size for me..the 24 inch.
I love it. It is helping me lose weight and get stronger. I couldn't be happier! I'd recommend it to anyone looking to buy a trike.
AVOID this Trike. It arrived with a very large gouge on the frame. The fenders rub, the front brake is not adjustable by me & i'm fairly handy. I will have to take this brand new trike to a bike shop to get the front brake working. Wheels are out of true. The whole thing just feels cheap. I am tempted to return it but I know shipping would be very spendy. DO NOT BUY This JUNK! !
I have absolutely no idea if I will like it or not as I just ordered it a little while ago. I have tried and tried to change the order but have NOT been able to do so. My computer seems to be working alright on everything else but Amazon. I am ordering the tricycle only. The other things I purchased before and have PAID FOR THEM.
If I ordered another trike I would have it assembled at a bike shop. We live 25 miles from a bike shop and have no way to transport it. When assembled it needed some fine adjustments that I wasn't capable of doing. Holding the rear chain tight during assembly was not for the faint hearted. My wife still doesn't ride it because the front brake pad is tight. Yes, I have followed the directions as best I could to loosen it. I know it still needs grease in spots.
Love the tryke... and so does everyone else! Would recommend it to people who never learned to ride a bike, but want to experience thrill of riding one.
I ordered a couple of  these for use on a college campus in the housekeeping and maintenance. I was wishing they were three or five speed to make it easier to go up the hills. After I assembled the first one I immediately to it up the longest grade we have with no problems. I'm actually glad they're single speed now because they'll have less issues later. Our hills are not real steep though for serious grades you'll want more gears.
Answer: no
