The wheels are equipped with brakes for safety. But the lack of features like reflectors and mudguards do hamper the safety of the bike. The shape of the handlebar is a bit inconvenient for beginners due to its upright profile. The handlebar can be adjusted to 6.5″ to account for height variations. Same goes for the seat post, it can be slid from 20″ to 24″. If your child is a beginner, then the provided training wheels might come in handy. The bike is suitable for kids 3 to 6 years old.

Paint Job

Diamondback Mini Viper Bike comes in two color options, i.e., blue and green. These color options are limited and may not satisfy the color demands of the kids. The overall bike looks average. The frame is colored, while the rest of its components are black. The black components complement the frame color. The paint is durable and does not easily chip off. It gives a matte finish to the bike. The large handlebar gives an alien look to the bike. It appears way too kiddish than other bikes in this price range.


Material and Strength

Diamondback Mini Viper Bike uses steel for its frame, which is an excellent material for resisting dents and other wear and tear. It weighs 20.8 lbs or 9.43 kgs. It is heavier than other bikes in this price range. Therefore small kids will find it challenging to handle and transport. The rims of the wheels are made of aluminum, while the handlebar is of steel. The coaster brake and steel pillar seat post contribute to making this cycle heavy-duty and durable.


Safety and Stability

Diamondback Mini Viper Bike has unexposed bolts which protect the kids from minor scratches and injuries. This bike lack reflectors, so it is not safe for the kids to ride this bike during the night. One of the good features of this bike is that it comes with handbrakes. Handbrakes save kids from unexpected collisions and keep them safe while riding. The presence of training wheels is an extra advantage of this bike. Most novice riders do not feel confident while riding the first time, but training wheels make this journey easy. So if your kid is underconfident in riding, training wheels will make the learning easy and develop their confidence. It can easily be removed after they gain confidence. The chainguard protects kids from accidentally hurting themselves. Handlebars grips are okay and do not slip while riding. The bike does not come with a stand, so kids will have to find a resting place for their bike. It also does not come with a mudguard, so kids will ruin their clothes while riding in mud.


Wheel and Comfort

Diamondback Mini Viper Bike comes in two-wheel options, i.e., 16″ and 20″. Larger wheels give the advantage of a comfortable and enjoyable ride, while the rubber air tires provide a good grip on slippery surfaces. Kids can enjoy their ride on any terrain because of the better traction of air tires.


As aforementioned, training wheels are of good quality and develop confidence in young riders. They can easily be removed anytime when kids don’t feel their needs.


The seat is padded and provides comfort to the kids. The rider can adjust the seat height up to 4″ ( from 20″ to 24″). It gives enough room for the growth and development of the kids. They don’t have to hustle themselves to learn balance and coordination quickly.


Diamondback Mini Viper Bike comes with upright handlebars, making the overall look of this bike a bit ‘bizarre.’ It can be raised to 6.5″. Upright handlebars are not a problem for experienced pedalers but could be more challenging for a new rider. So your kid may be uncomfortable in the starting days while riding this bike. The handlebar grips are not that great but do their work sufficiently. The wide resin platform pedals provide enough room for the kids’ legs. It allows the kids to ride their bikes without exhausting much energy.


Extra Features

Since the company does not have a proper website, add-ons can only be purchased from somewhere else. This bike places riders in an upright position and thus maintains a correct posture, which is necessary for the proper development of the kids. This bike comes with minimal assembling, so all you have to do is put on the front wheel, seat, and pedals. The brakes are dialed in, and the gears are adjusted. So just pump up the tires and go.


The company provides a lifetime warranty on the bike. It also offers good customer care support. So if you face any issues, you can get in touch with the company’s executive to resolve your issues.



Concluding, this bike does not provide good color options, so it may not attract the little riders who are very color-conscious. The overall look of the bike does not appeal much because upright handlebars make it look weird. But the paint job is satisfactory and durable. This bike uses metal to construct its components, thus making the bike very durable and heavy-duty. However, this durability comes with the cost of being heavyweight. The weight is not suitable for small riders. They may face difficulty while riding this bike. A padded seat, chainguard, adjustable handlebars, and larger wheels are some of the remarkable features of this bike. However, this bike lacks a mudguard and a stand. This bike is designed for 3-6 years old kids.
