MongooseCipher Kids Mountain Bike Blue, 20-Inch or 24-Inch Wheels

Components supplied were different than those in pictures.Supplier sent a 3 speed nexus bike, even though description clearly said 7 speed nexus.Chain guard was different etc. than in photos.All together poor performance.Not a good experience.

I have no idea if this is a good bike or not as my daughter couldn't ride it. She is 4'6 and the 20" size is recommended for 4-5 ft. 24 is recommended for 4'8+. DO NOT BUY IF YOUR KID IS OVER 4'2

This lightweight, yet sturdy mountain bike is ideal for our ten year old. We ordered the 24” wheels with alloy V-brakes. All parts and pieces look well-made, except the brackets for the rear red reflectors that are supposed to mount under the seat are too small to fit the seat post. That’s the only reason it’s receiving a four star rating instead of five.The parts that require assembly are the handlebars, front wheel, front wheel quick-release lever, pedals, and the seat post with the seat already attached. The owner’s manual provides clear instructions with detailed illustrations. There were no surprises during assembly. You don’t have to be a bicycle specialist to assemble and fine-tune some of the working parts, but a basic familiarity with how multi-speed bikes work will help. No rear derailleur adjustments were necessary and the front brakes needed only minor fine tuning. Beginners will appreciate that all seven speeds are controlled by a single twist shifter, which operates smoothly. The chain is kept centered on the front pedal sprocket with a type of chain guard that should help keep pant legs from getting caught between the chain and the sprocket.I’ll use a hex wrench to adjust the handlebar angle as our child grows and raise the seat with the quick release lever. The bike has a clamp (headless) handlebar stem, which can't be raised, but it does angle for a more comfortable ride. Our ten year old really likes the bike's sporty colors, and the way it handles on all types of terrain.

You get a flat box with some assembly required. I ordered the 24 inch and ended up with the 20 inch so I will go ahead and write up what I found on the 20 inch. Assembly was easy with basic knowledge, skills and tools. The 20 inch comes with both the rear hub brake and hand brakes as an entry for young riders into the full size bike setup without taking away the security of their tried and true braking system. As a kid I hated this kind of bike but as a parent getting this bike for a younger rider just makes sense. The 20 inch is not a trick bike or anything like that, it is an entry level bike into the trail and off road biking scene and this bike is very high quality for just that. Great off road capability and very fun to take on the biking trails. It has a hardtail design which helps with rigidity and prevents unexpected breakdowns on the trail. All in all this is an excellent entry level off road bike

Our 11 yr old grandson admires the bike and would love to ride it but he can't stand the seat so he'll just admire till some adult gets a seat for him. Weather hasn't been that good, drizzle and rain, but it won't be long and it will be spring and bike riding will be at the top of his list. He hasn't had a chance to ride much but is ready to use the Mongoose. I learned a lot from reading the other reviews lol It does feel like wonderful bike, not being heavy makes a world of difference IMHO My husband and the boy put it together without any problems but the red lights don't fit!The price overwhelmed me lol but that's because I haven't looked at a bike to buy forever it seems.
