* Note on Age: Razor’s recommended age for both the RSF350 and the MX350 is a highly conservative 13+ but an age range of 5-10 (real world guide from many buyers) with parental supervision may be more suitable. Because both these bikes are very small – the seat height is only about 20″ which is at least 14″ lower than a regular, adult sized dirt bike.
Check out the videos in the next section for a real world view of the appropriate ages for these bikes. The first video shows 4 and 7 year old boys riding the MX350 (which is basically the same size as the RSF350) – teens just aren’t going to fit…
The biggest difference between both models is the style of bike and the type of terrain that each was designed for.
The RSF350 is a street bike with standard tires on 10″ wheels whereas the MX350 is a dirt bike with knobby tires on 12″ wheels which make it more suitable for riding off-road.
The RSF350 is also 18% lighter (51 lbs vs 62 lbs) so is easier to lift up and it has variable speed for smooth power delivery whereas the MX350 is single speed (on or off) which can make the start quite jerky.
However the MX350 does come in a wider selection of colors (blue, red or black) whereas the RSF350 is only available in red.
Advantages of Razor RSF350 Street Bike
Both these bikes have very similar specifications so there aren’t too many advantages compared to the MX350:
- Variable speed provides smoother power delivery and a less jerky start than the MX350 which only has a single speed (i.e. either on or off)
- The RSF350 is 18% lighter (51 lbs vs 62 lbs) so is easier for small kids to ride and to lift back up off the ground if it falls over
- Hidden compartment for storage (on top of the bike, a flap above the Razor logo lifts up to reveal the compartment)
- Occasionally on offer cheaper than the MX350 but check the actual price below
Advantages of Razor MX350 Dirt Rocket
Likewise, the MX350 doesn’t have many advantages over the RSF350:
- MSRP (Manufacturer’s Suggested Retail Price) is about $30 cheaper than the RSF350 – but check the actual price below
- Larger wheels with knobby tires provide better traction and ride comfort, especially off-road (12″ vs 10″ wheels on the RSF350)
- Available in 3 colors (red, black, blue) whereas the RSF350 is only available in red
Pros of Both Bikes
Here is a summary of what we love about both models:
- Specifically designed for very young children with user friendly controls
- Adjustable angle handlebars can adapt to fast growing kids
- Quick enough to give kids a thrill but slow enough to minimize risk of a high speed crash
- Pneumatic tires (unlike plastic tires of cheap bikes and ride on toys) can tackle many ground conditions including some light off-roading (especially the MX350)
- Steel frame with authentic street-bike styling or motocross frame geometry
- No pollution (compared to a gas dirt bike)
- Quieter than a gas dirt bike and requires much less servicing
- Razor is a long established US manufacturer – spare or replacement parts are readily available from their website
Cons of Both Bikes
Here is a summary of what we don’t like so much about both models. But most of these issues are common to all electric dirt bikes in this price range:
- Relatively short battery life. But 30 minutes is still enough to cover about 7 miles
- Battery full recharge time is 12 hours so charging needs to be planned (or you could buy a spare pair of batteries to switch over instantly)
- No headlights or rear lights – can only be driven in daylight
- Helmet and protective clothing (see our Electric Dirt Bike Buying Guide for recommended safety gear) may be uncomfortable in hot weather
- Must be stored in a dry area, due to the electrical components
- Batteries must not be stored in temperatures below freezing and should be recharged at least once a month
Both these electric bikes can be a good choice for young kids aged about 5-10 years old. They are almost the same size and have very similar specifications which makes it tough to pick a winner between them.
So which model is best? We think the best choice depends on the type of terrain that the bike will be used on most often. For mainly off-road riding the MX350 is the better bike, thanks to its off-road knobby tires and larger wheels.
Whereas the RSF350, with its street tires and variable speed, is the best choice for riding on hard flat surfaces like concrete or dry grass/dirt. While it is capable of venturing off-road occasionally it won’t have as much traction as the MX350.

NOTE: A parent’s decision to allow their child to ride either the Razor RSF350 or the Razor MX350 should depend on the child’s individual maturity, skill and ability to follow rules.
