The world of small electric dirt bikes is increasing every day. But, how do you tell the difference between something that will handle a big send on a track, vs something great for mucking around on, on the flat, more carefully?
There is a huge range in capabilities, all made for different purposes. Some are great for lightweight kids, some are made for ripping. Some have great warranties and aftermarket support, some are made more for the toy store. Some will survive a backflip, others won’t…
You could go on price and assume more expensive is better, but what is it that you’re really getting? And why? More power could mean it will survive an MX track, but what about the other components? Will the brakes hold up? The suspension?
There are so many questions when it comes to choosing the right small electric dirt bike, but the very first one needs to be ‘why?’. Do you want something that will last, survive a good track for both adults and kids? If that’s the case, then head to any reputable dirtbike dealer. We are official Electro and Co and MotoTec dealers, and our bikes can withstand just about anything! (Check out what we get up to on YouTube or Instagram!)

How Electro and Co, Razor, and MotoTec are related:
Any quick Google search will show these small dirt bikes are somewhat intertwined, and this is why:
Electro and Co, a company that has been creating high-quality, plug and play electric powertrain kits for dirt bikes and pit bikes for ages, teamed up with Razor to create the Razor MX Pro Spec. So, in its stock form, you can purchase the 5kW Razor MX Pro Spec from either Electro and Co or the Razor website.
However, as Electro and Co. had something to do with the build, in Electro and Co fashion, you can upgrade the powertrain with an Electro and Co kit, to bring you some extreme power. Easily.
You’ll also notice that Electro and Co sell MotoTec parts, mainly for the smaller-sized MotoTec electric dirt bikes. This includes power upgrade kids, brake parts and more all designed specifically for the MotoTec.
Then, Electro and Co, since being part of the Razor MX Pro Spec build, have created their own electric dirt bike known as the ETM RTR.
Let’s look at each of these small electric dirt bikes individually, then work out which would be best suited to you.

Electro and Co ETM RTR
Electro and Co ETM RTR specs:
- Power: 72v 25Ah 8kW (upgradable to 45Ah battery)
- Motor: E&Co ETM IPM Brushless motor
- Battery: Up to 30 miles (stock battery)
- Charge time: 1 – 4 hours, depending on the charger
- Weight: 130 Lbs
- Tires: MX 60/100-14, 80/100-12
- Seat height: 30”
- Suspension: 48mm E&Co Tuned Dual Adjustable Forks
- Brakes: Lightweight E&Co Pit Bike disk brakes from and rear
The ETM RTR is the first complete bike from California aftermarket parts maker Electro and Co. The name is an abbreviation for Electric Trail Machine, Ready To Rip. Powertrain numbers are 72v 25Ah 8kW, range is 30 miles, and weight is 130 pounds.
Known for innovative electric powertrain conversions, Electro and Co are no newbies to high-powered, quality builds. The ETM RTR is designed to withstand hard riding right from the start. The frame is super strong, designed from high-grade materials, and even the swingarm has been designed to prevent unwanted flex.
However, the biggest standout feature of the ETM RTR is how it’s been designed with upgradability in mind. While it’s awesome as is, we’re inclined to mod everything we can, so this makes upgrades simple.
To see what we’ve put the ETM RTR through, check out this video:
The build quality of the ETM RTR is fantastic, in fact, we think it could be better than some other well known mid-sized electric dirt bikes. This article explains more about the ETM RTR
MotoTec 72V Pro 5000w
MotoTec 72V Pro 5000w specs:
- Power: 72v 32Ah 5000w
- Motor: Brushless – Rare Earth Neodymium Magnet
- Charging time: 6-8 hours
- Weight: 176 Lbs
- Tires: Front: 70/100-17, Rear: 90/100-14
- Seat height: 35”
- Suspension: Dual hydraulic front shocks
- Brakes: 220mm front and rear hydraulic disc
This zippy electric dirt bike has a slightly slower top speed than the ETM RTR, as you can see from this video, and it’s rated at 5000W, which is also less than the ETM RTR. The MotoTec 72v electric dirt bike falls mid-range between the Razor and the Electro and Co, which is reflected in the price.
With 3 power options, the MotoTec is a great option for those riding at different experience levels.
The MotoTec is the largest in size from the ETM RTR and the Razor, with 17-inch front tires and 14-inch rear, and a seat height of 32”. This electric dirt bike is also much heavier than both the ETM RTR and the Razor, coming in at 182 lbs.
For this price range, the MotoTec is a solid build. There are many options for upgrades on this bike, but keep in mind if you’re looking for a pitbike to take around the MX track, the upgrades needed will end up being more in price than the stock ETM RTR.
Here is an interesting video on upgrading the throttle on the MotoTec Pro 5000w with an Electro and Co throttle.
Razor Dirt Rocket Pro Spec
Razor Dirt Rocket Pro Spec specs:
- Power: 48V 20Ah 1600W
- Motor: Variable speed, high torque
- Weight: 106 lbs
- Tires: Front: 14”, Rear: 12”
- Suspension: Front: Hydraulic coil sprung, Rear: Link tuned, 120mm of travel
- Brakes: 180mm front and rear
The Razor is the cheapest pitbike-sized e-moto in this comparison, the lowest powered, but the lightest. It could be considered your entry-level electric dirt bike, made specifically for people 16 years and older.
As you might expect, it isn’t built to the same strength as the ETM RTR. In other words, I wouldn’t go launching myself off a jump without modding quite a bit on this bike first. However, it depends on what you’re after. If you want to have fun ripping around on a flatter surface, without putting too much loading on the suspension, it will be perfect fun. Not everyone wants to get airborne. If that’s you, the Razor could be what you’re looking for. Also, for those brand new to dirt bikes in general, your skills won’t outride the bike… for now.
This is where Electro and Co. come in. If you’ve got yourself a Razor Dirt Rocket Pro Spec, you could consider upgrading the powertrain with the Electro and Co Extreme Kit. This kit beefs up the power of a Pro Spec to a crazy 14kW!
Side note, if you do consider upgrading the Razor Dirt Rocket Pro Spec with the Electro and Co Extreme Kit, seriously consider also beefing up other components to withstand the increased power. Think: forks, rear suspension and linkage, brakes. The price will be coming close to the ETM RTR, so consider your long-term plan when purchasing a Razor.
Here is a great video about upgrading the Razor Dirt Rocket Pro Spec with the Electro and Co powertrain:
ETM RTR vs MotoTec 72V 5000w Pro vs Razor Dirt Rocket Pro Spec
Each of these three e-motos serves a different category. From an entry-level, muck around bike, the Razor, to the high-end ETM RTR, there is something for every experience level and riding style.
If you’re in the market for a small-sized e-moto, firstly, consider how you’ll be riding it. What do you want from a bike? I would be staying away from the electric dirt bikes you find at some toy stores, the bikes that are only a few hundred dollars with questionable parts. At a minimum, the Razor bikes would be a good starting point for any age.
Which bike should I get?
- ETM RTR: Serious riders and those wanting a bike great from stock (that’s also easily upgradable), something you can take around an MX track, jump over mounds, and more.
- MotoTec 72V 5000w Pro: Riders wanting a good bike, but not keen on heading around an MX track or placing too much loading on the suspension.
- Razor Dirt Rocket Pro: Entry-level riders who want a bike at an entry-level price.
What upgrades can you do?
The ETM RTR is the easiest to upgrade, not that it needs it. Upgrades on the ETM RTR occur because you want to tailor the bike to you, to get even more performance out of this machine. The ETM RTR was made with modding in mind, because, why not!
Head to GritShift.com to find all your modding needs for the ETM RTR. Change the wheel size, customize it into a Street Machine with the 14-inch Street Wheel set, upgrade the power, and almost anything else!
Electro and Co. provides upgrades for the MotoTec and the Razor, from upgraded wheels and brakes to upgraded powertrains. Keep in mind, if you’re upping the power on these e-motos, consider upgrading other components so they can handle the increase in power.
