A: No, the MX350 is designed for riders aged 13+ with a maximum weight limit of 140 lbs. The height from the top of the seat to the ground is 19".

A: I'm 5'3" and have ridden it with my son, it's fun for a while but you may be upgrading to a larger frame quicker than my 8 year old.

A: My sons 5 and he has it and hes fine

A: My son is 8 and I was concerned as well but he's having a blast on it! We started off with protective gear until he got comfortable enough to drop everything except for the helmet.

A: Just purchased this item for my 6 year old daughter and 4 year old son. :)

A: The MX350 is designed for ages 13 and up. An 11 year old riding it would depend on the maturity; skill level, size and ability of the individual child. The next size down would be the MX125 which is designed for ages 7 and up.

A: My 8 year old son has a blast on it but he also started riding his bike at 3.5 years old. I'd go with your instincts and your kid's ability to ride independently.

A: This depends on the consumers skill level, roughly about an hour!

A: Actually it takes about 15 minutes.

A: Assembly instructions are included in the owners manual!

A: 1. Bolt the handlebars to the brackets to the top of the forks. 2. Patch the front fender using a single Bolt. 3. Secure the number plate using the snap on pegs. 4. Ensure tire pressure is 45 PSI. 5. First charge charge for 12 hours even if the light turns green. Took me about 15 minutes to assemble the hardest part is waiting for the first 12 hour charge.

A: The only thing that needs to be assembled is... 1. The handlebars need to be put on brackets and bolted to the top of the forks. 2. Then you put the front fender on with one bolt 3. Then you put on the number plate which snaps with pegs. 4. Then you check the tire pressure, should be at 45 PSI. (Even though the manufacturer ships inflated and they may feel inflated, they definitely lose air over time. My tires were at 20 psi at unboxing) 5. Charge for a full 12 hours the first time even if the light turns green.
