Looking for an electric bike that can really deliver? You’ve arrived! The X-Treme Rubicon Mountain bike cranks out 500 watts, along with the high-torque Bafang clutch motor as a powerful addition to this already robust bike. The Rubicon 48-Volt lithium powered e-bike delivers a smooth ride with substantial power. Made from hand-welded premium aluminum, it is built to last and designed to perfection.
Made with aluminum wherever possible, this means no rust and a robust bike that is built to withstand the test of time. The completely hand-welded aluminum frame bike has 9-Speed Gears and a shifting system by Atlus Shimano, KS Rear Shock Suspension, Suntour XCT Front Suspension & aluminum rims with a fast release axle on the front and a quick disconnect on the back. The lithium LiFePo4 battery is compact, it’s light, and it mounts to the down tube of the bike frame. Because it is the same color as the frame, it is hardly noticeable.
The Rubicon has a King Meter 5-speed SPAS, and all electronics are fully controllable from the LCD on the handlebars. This is because you can choose the consumption method on the LCD easily. The LCD will also tell you the remaining battery, the distance traveled, and your speed. There is also a convenient USB phone charging port.

Using Smart PAS will allow your X-Treme Rubicon 48V electric mountain bike to achieve up to 70 miles + before it needs charging again (applicable while using a lower SPAS and pedal assisting on level ground under optimal conditions with a light rider.) The Rubicon bike is faster than any model we sell.
Both front and rear Tektro disk brakes are standard on the electric Rubicon e-bike, ensuring you get sharp and decisive breaking that responds rapidly at all times. The full suspension soaks up all the bumps of the trail or road. Combined with the ultimate VELO hand grips and seat, your ride comfort is absolutely taken care of. A rear rack to hold your belongings is also included.
If you opt to ride the bike with no electric power, you will not be able to feel the resistance of the motor when cycling. However, with a powerful 500-watt, no-resistance, gear rear hub motor and a 48-V battery, this bike can climb hills like a beast all day long. The big disc brakes will stop you as fast as you can get going - even in wet conditions.
The all-new X-Treme Rubicon is better than ever. It is one of our most popular electric mountain bikes as it offers the full suite of benefits: Speed, Versatility, Comfort, and Affordability.

There are three classes of electric bikes:
Electric bikes can be used during rainy conditions, but you should take care not to soak the electric motor, computer controller, or battery. When you get home from a wet ride, the entire bike should be wiped down with a dry cloth to remove excess water.
Please be cautious, because riding any bicycle in rainy conditions can be hazardous, and you should only do so if you feel comfortable controlling your bike. Take turns more widely and slowly than normal, look out for puddles (which might be deeper than they appear) and please always wear a helmet.
The short answer is yes but not much. The effect of weight is largely exaggerated in how a bicycle performs. A heavier bicycle is slightly harder to ride uphill, somewhat faster to ride downhill, and pretty much the same on the flat as a lightweight one.
The addition of a motor and batteries can add anywhere from 15 to 30 lbs to a bike and has surprisingly little effect on its rideability. You definitely do notice the weight if you have to pick the bike up and carry it for any reason though, and it can be a bit unwieldy.
Electric bicycle (e-bike) laws are different in every state, and can be confusing for consumers, retailers, and suppliers. This map represents how e-bikes are interpreted in each state’s vehicle code for use on the road, bike lanes, bike paths, or other paved or hard-surface bicycle infrastructure. The vehicle code does not apply to electric mountain bike access on motorized and non-motorized trails typically used for hiking or biking. eMTB access is not addressed in state vehicle codes. Always consult with your local land manager for eMTB access questions.
The average power that a typical cyclist will deliver is on the order of 150 watts, or 1/5th of a horsepower. If you're curious, most modern exercise bikes will display the exact wattage and you can get a feel for how much power you're producing with the legs.
A fit individual can sustain 350 watts for about 10 minutes and up to 600 watts for a few seconds, but for continuous riding between 100-200 watts is typical. You might think then that 150 watts would be all you need for an ebike, but if you ever ride a 150 watt bike it will feel unimpressive. When a cyclists hits a hill, they switch to an easy gear and the speed drops to 10-15 km/h as they work hard and move at a slow pace. However when an electric bike does the same thing and slows to walking speed on the hills it seems way underpowered. To maintain nice speeds over 30 kph while going uphill requires on the order of 400-500 watts or more. On the flat, 400 watts (about 1/2 horsepower) will move a typical bicycle about 40 km/h.
This is one of the most commonly asked technical questions we get and it shows that the advantages and capabilities of electric drives are widely known. The answer is that yes, on most hub motor ebikes it is possible to recharge the batteries from pedaling. BUT, only when you are moving at a speed faster than the motor can attain itself.
Recharging from pedaling is not really the intent of the electric drive as it is with, say, a hybrid car. In general, with an ebike you draw a net amount of power out of the battery pack to assist you riding. You then replenish this energy from the wall outlet, rather than by working extra hard later on in the trip.
The topic of regenerative braking comes up quite frequently, and the point here is not to recharge the batteries from your pedaling energy, but to recharge them from stored kinetic energy when you come to a stop. With any direct drive hub motor or geared ebike without a freewheeling motor, you will get regen currents when you are moving faster than the unloaded speed of the motor. So even though it won't bring you to a stop, it does act as a speed governor of sorts for long downhills, dumping the extra energy back into the pack, whether you want it to or not. In most cases it's quite rare that you would actually achieve speed greater than the unloaded speed of the motor for any length of time.

Is the bike waterproof.
The bike is water resistant not waterproof. It is fine to ride in light to medium rain.
What is the top speed on this bike?
Depends upon many factors. Weather, weight of rider, terrain, and battery charge. Typically up to 25 mph.
Hi,is it possible to change the handle bar for one who turn to your body,so it is less harder on my injury back. Secondly,I am a Canadian living in Montreal and is it free shipping to. Robert Milton Milton.robert81@gmail.com Thank you.
We do not do any modifications of the bikes we sell. One would need to contact a local bike shop for modifications. Sorry. We do not ship to Canada.
