Question: what is the product weight? I plan to buy one and bring it to Japan. Yet airline weight limit is 45 lbs per bag
Document: I saw the WingFlyer at Fireworks at the Fountain on July 4th in Orlando and had to have one. The general consensus amongst the crowd was that nobody had seen anything like it. I tried the product there and decided I had to order one. The WingFlyer is very easy to assemble out of the box which adds the the "easy to use" mentality they portrayed.
On a separate note, Zike is committed to their community and is a responsible corporate citizen, making charitable donations whenever they can. I love a great product, but I'm most definitely a sucker for a company that gives back -- Zike is great and I encourage anyone to give their products a try!
It only takes one word to describe the Wing Flyer and that word is Fun. Every time I ride it, I get stopped by people wanting to know what it is and if they can take it for a spin. Not only is it fun to ride, but it's a great work out for your legs and glutes (it's like a stairmaster with wheels).I was also very happy with the service I received from Bike Liquidators. My Wing Flyer arrived sooner than expected.
I had not been able to ride a bike in over 10 years thanks to back surgery and a delicate tailbone. When I first heard of this I was curious but skeptical. I tried one at a local bike store and the rest is history. Not only is this thing a great workout, not only is it TOTALLY fun, but it allows me to re-live that feeling I used to get riding a bike, only FUNNER!!! Thank God for this thing.
I bought this so I could keep up with my kids on their Razor or Go-Ped kick scooters. As a tall adult, this isn't really meant for me, but that's OK - I didn't want to buy the much larger bike version - too hard to carry.
The wingflyer is a great product to get exercise while being outside. I bought a small wicker basket from Amazon to put on it, so I can carry water or ride it to a nearby store. I'm still conditioning my legs to go further distances on it. Definitely will get your heart pumping & legs strong. Love the fact I'm not stuck in a gym staring at a television. I'm hearing birds sing instead.
"Step cycle" is the most accurate way I would describe it. And for those of you who are vain, you'll get ALOT of compliments from people of all ages while riding this thing. But that's the least important reason to get it. Get it because it's healthy, and if you can't ride a bike because you suffer from back problems, you owe it to yourself to try this out.
both?) itself: I will begin by saying it's very unique... like nothing I've ever tried before. It's hard to imagine if you've never seen it, but the best comparison I can make is that it's a stair stepper on wheels. The motion is up and down with each leg; truly as simple as that. However... as simple as the process is, the workout you receive from the WingFlyer is intense.
Zike offers fun, creative products for children of all ages. UNIQUE and FUN are the best words to describe their scooters! I work for a non-profit organization in Greenville, SC (where Zike company headquarters is located) and have experience with their products both as a consumer and as a beneficiary of charitable donations of the Fly-By Zike.
By the end of 30 minutes on the WingFlyer, I was feeling it! Also of note: as someone who now experiences joint problems due to a once physically-demanding college athletics career, this exercise was ideal because it is extremely low impact.All workout benefits aside, this machine is downright fun. Because it's so different, part of the fun is seeing how people look at you when riding it!
