Question: My son is 40 inches.  Will he be able to ride it?
Document: I bought this bike for my 5 year old twins, and they LOVE it!! It is so much fun. Great quality, and they will be able to use it for years. I'm 32 and I love to ride it too! !
The toy indicates six years old plus, also 160 pounds maximum weight. My grandson is eight years old and 100 pounds and the toy is virtually too small for his legs to pedal by extending his legs, cramped. He loves the toy, but barely able to ride it.
Great outdoor toy! We bought for my 7 year old son for Christmas present. My son, 13, was able to put it together- very easy. And both are able to enjoy the they loved! Lots of fun specially with the sparks! I would recommend to use a helmet.
The sparker falls off all the time which is a problem. But my son and his friends ride it all the time.
The bike was great my son was so excited to ride it but the first time he tried to pull bar to make the bike spark the sparkler fell off.
Bought this for our 6 year old son for Christmas. Took it out for a ride Christmas day and the very first time he used the spark bar it broke off.
My son (5) and husband (28) love riding this fun twist of a bike. DO NOT let them ride near streets because it does not necessarily go where you think it will.
My son had seen these at his school and wanted his own. He took his Christmas money and purchased it. It is amazing. All the neighborhood kiddos love it too. They love how it makes sparks when you brake. We have even had 130 lb people ride it! Pretty durable
Great fun ride. My kids love it, however the spark cartridge broke after just a few uses on the first test run. My friends son also got one of these for Christmas and the same thing happened. Order extra cartridges.
Hours of fun! My 6 y.o. Son loves to ride his bike. Everybody stops to watch him spinning...he is the focus of attention in the park!The only bad thing is that the spark housing cartridge melted during his very first ride. This problem was noticed by other reviewers too.I suggest to tell your kids to use the spark handle not longer than 2 seconds and wait at least one minute to avoid melting of the spark cartridge
Answer: yes
