How fast does the mx650 go

Thank you for all the detail in your answers. When do you think the 48v w kits with the 72 tooth sprocket be available? Regarding the chain, it doesn't look like the 8mm chain is that much bigger than the 25, so do you think an even larger chain should be used, or has the 8mm proven to be reliable? And I assume that the kit comes with a new motor sprocket as well as a wheel sprocket? Regarding run time. Thank you for including that link. For some reason I just could not locate it on your website.

It looks like the run time with this w motor on flat ground using the 4 x 12v 15ah batteries would only be about 30 minutes and even less if there are hills. Since space is at a premium, I'm going to have to find a lithium battery that will fit, so my question is do you have adapters to fit?

Instead of 4 SLA batteries, it looks like most 48v lithium batteries will be just one or maybe two, so the wiring will be different. We should have the 72 tooth sprockets in around three to four weeks.

We do not see any reason to increase to a 35 chain and add the expense and weight of such a large wheel sprocket and chain. Our Watt MX dirt bike kits have both sprockets and a chain included. They have everything needed for the modification with no other parts needing to be purchased. We can work with you on the lithium battery pack adapter once you know which battery pack you will be getting. Once we know what type of power connector the battery pack has then we will be able to make the adapter for it.

I was thinking that since I have 3 Razor MX's for my three kids that all weigh about the same, I would do a little comparison to see how much each different upgrade affects the performance of the dirt bikes.

I'm going to upgrade all three of the dirt bikes to the 48v w kit and add Lithium batteries. But since I have one stock MX with the standard 12v 12ah SLA batteries in great shape, I'll upgrade that one last to have a base line to judge the upgraded performance of the other two against.

One of the other MX's I'll just upgrade at first with the 48v lithium batteries to Overvolt the motor and see how much performance increase I get just from doing that. Then the third MX I'll put in the lithium batteries along with the 48v w kit. This way I can line them up next to each other and have a direct comparison to judge the increase in acceleration and speed, as well as the torque on the hills. I think I would prefer to have the upgraded kit with the 72 tooth rear sprocket versus the 63 tooth rear sprocket, but perhaps I'll go ahead and order the 63 now.

Then when the 72 tooth sprocket comes in I can order that one and switch them out? This will give me a chance to compare both sprockets against each other and provide those results. I'm still uncertain about which type of lithium battery to buy for this project.

I've heard so many horror stories about the poor quality of the Chinese made batteries, but the American made lithium batteries are very expensive. Also, I understand there are many safety concerns about certain lithium batteries? The LiFePo4 seems to be the safest, but also the largest and heaviest. Does anyone know if the newer Lithium NMC batteries are safe enough to be in one of these dirt bikes?

Does anyone have a link or links to any threads on this topic? If anyone has recently upgraded to lithium, I would appreciate any help on this matter so I can go ahead and get the batteries to get this project started. Thanks again. Those all sound like a great ideas.

Maybe someone else reading this has more information about the NMC batteries though. I have a standard E and want more torque to climb hills. Speed is not a factor - 5 or 6 MPH would be fine. Will an 80 tooth sprocket fit? I have a razor mx and I had a custom sprocket made for me by ElectricScooterParts. Top speed is 14mph and run times are super good.

Im lbs and it pulls me up hills just fine. The MX is an awesome e bike and worth every dime. The MX will accept a larger rear wheel sprocket and a tooth sprocket for 25 chain should fit, not so sure about a tooth sprocket for 8mm chain though. I would check for clearance before ordering a tooth sprocket just to be sure though. We have a Sprocket Diameter Calculator which can be used to determine the outside diameter of a custom-made sprocket before you buy it.

The MX rear wheel freewheel has a F4 mounting pattern and when custom ordering a sprocket from us you can specify an F4 mounting pattern when requesting a price quote for the sprocket.

The SX is rated to support lbs and the MX is rated to support lbs. Both have the same seat and handlebar height. The following sprockets could be installed on the MX or MX to increase the gear ratio for a faster top speed:. The sturdy, steel construction guarantees quality and its authentic frame geometry help to generate additional power when going uphill.

Its maximum speed is 22 mph which makes it the fastest Razor electric dirt bike. At 30mph, you are going to be driving more than fast enough for most local trips. Driving around a town, city, village, or local area is much easier at 30mph. The Size of the Razor Dirt Bike These little bikes are safe and quite handy when it comes to riding them along the rugged terrain or unpaved surfaces.

When choosing the best model for your young kids, you need to start by looking at their respective ages, weight, height and riding experience. What is the fastest electric dirt bike?

The Zero FX can reach a top speed of up to 85 mph, making it one of the fastest electric dirt bikes. With a high torque motor, large, knobby tires, and speeds up to 12 miles per hour, the MX leaves similar pocket dirt bikes in its dust. The MX is the best Razor dirt bike for riders ages 16 and older with a maximum rider weight of pounds. In short, the most noticeable difference between the MX and the MX is that the MX is powered with a watt motor and the MX uses a watt motor.

So, what is the top speed of a cc go-kart? This heavily depends on track conditions, driver weight, engine type 2-cycle or 4-cycle and a whole host of other variables.
