General Information

• Get a battery pack that goes at least twice the range you usually expect to ride.

• Range is proportional to battery size; twice the battery size = twice the range.
• For every two miles you go, plan on about one hour of charging and about one cent of electricity.
• When speed increases, range decreases even faster; 1/3 faster = 1/2 the range.
• A 400-watt motor takes an average rider up all but the steepest hills (but weak controllers can limit performance).

Two 12-volt, 12 amp-hour batteries will take an average rider 10 miles at 15 mph or up a hill that’s 800 feet tall.

e-bikes by Revolve were designed to go the legal speed limit of 20 mph with most models averaging approximately 18 mph.
Depending upon battery capacity, weight, speed, and terrain, e-bikes can range between 20-30 miles before the battery needs recharging – making it ideal for commuters and light errands.
No, the electric motor is very quiet. The e-bike looks, rides and sounds like a standard bicycle.
Absolutely! Power-On-Demand means just that- no pedaling required. Although all electric (or “electric-assist”) bikes are designed to work with your pedaling, power-on-demand allows you to break the rule. Most systems offer a variable speed control, although some are simply on/off. A “ped-elec” won’t deliver motor power unless it senses you are pedaling. And it’s “power output to pedal pressure” ratio is often adjustable. Most people find 350-watt motors adequate for their needs, although folks with steep hills may want more power. Some bikes offer through-the-gearing power assist – i.e. the force of the motor goes through the bike’s gearing system – which provides better hill-climbing and top-end speed than direct drive systems with motors of the same wattage rating.
Yes, Federal Law (US Public Law 107-319. 2011) exempts electronic bicycles, where top motoring speeds are less than 20mph, from laws governing automobiles and motorcycles. However, some states and local governments may have requirements that are more stringent than the federal law, which may apply to the use of electric bicycles, (i.e. age requirements, helmets, lower mph limit).
For most states a low-speed electric bicycle does not require registration, insurance, license plates (tags), or a driver’s license. The rules of the road for an electric bicycle are the same as a traditional bicycle. However, please check with your state for specific codes and requirements for e-bikes. For more details, visit your state’s DMV website for specific ordinances regarding electric bicycles.
In 2001, the U. S. Congress passed Public Law 107-319 which exempts electric bicycles under 750 watts/20 mph from the definition of a motor vehicles. “For purposes of motor vehicle safety standards…”, which means that the manufacturers of these bicycles don’t have to meet federal equipment requirements, and are instead governed by the manufacturing requirements of the Consumer Product Safety Act. There is no mention of exemption from other federal, state, and local traffic laws or exemption from the definition of a motor vehicle for other purposes.

Various states have passed their own laws. California law states that no driver’s license, license plate, nor insurance is required. You must be 16 years or older and wear a standard bicycle helmet. Electric bikes are subject to all the rules of the road, and additional laws governing the operation and safety of electric bicycles may be extended by state or local governments. It’s legally a bicycle, so you can use it wherever and however you can use a bike. Washington law is similar.

Federal law trumps all States’ laws. That is true with bicycle law, too. States cannot constitutionally pass legislation that reduces or eliminates Federal laws; they can only pass legislation that enacts additional (tighter) restrictions on its people. This means that no State can enact legislation that allows wattages or speeds greater than the Federal Government’s limit of 750 Watts and a top electric-powered speed of 20MPH. States can only legislate LOWER wattages and top-speeds (which, to our knowledge have not been done by any state). An e-bike can go over 20 MPH, but not by means of the motor. No matter what state you bike in, bicycle speeds on public roads above 20MPH cannot legally be motor-assisted. As a practical matter, police don’t notice bikes going too fast.

If you live in a state that lacks basic electric bike legislation, consider this. Although riding your electric bike may be illegal, so is jay-walking. Generally speaking, 1) police don’t know the exact rules, 2) police expect electric bike and scooter riders to wear a bicycle helmet, 3) most electric bikes look to the casual observer like ordinary bikes, and 4) if you get ticketed, just go to court and plead your case; judges usually let you off with a warning. And start working your state legislature to enact an electric bicycle law similar to California’s.

No insurance is required to ride an e-bike. However, if you want to insure it against theft, check your current homeowner’s insurance policy. An electric bicycle may be covered. To determine coverage, check with your insurance company or agent.
It certainly is! Unlike internal combustion motors in cars, buses, trains and motorcycles etc., the e-bike by Revolve uses safe, rechargeable batteries that do not omit noxious fumes and greenhouse gases into the environment. Electric bicycles are considered ZEV (Zero Emission Vehicles) and qualify for electric vehicle credits. Recharging a Revolve e-bike costs pennies per hour with a full recharge taking only 4-6 hours.

Not only is your e-bike by Revolve eco-friendly – it will save you money while you get fit and enjoy the fresh outdoors!

Yes. While some communities only define ZEV’s as car replacements, others are looking for alternative ways to reduce sources of mobile pollution. Electric bikes have qualified for electric vehicle credits in some communities. Check with your local environmental management group for clarification. Every time you take a short trip on your electric bicycle rather than a car, you delete a cold start that would have added a significant amount of pollution.

How e-bikes work is by assisting your pedaling. Electric bikes are everyday bicycles with an added battery-powered electric motor. Although capable of pushing you along without your help, electric bikes perform noticeably better when you pedal. The average “couch potato” who normally rides at 10 mph can ride at 15-20 mph using the same effort. He can also expect a range of 10 miles, with a recharge time of several hours. Do you remember that easy pedaling after you get your bike up to speed? That’s the cruising feeling you get all the time with an electric bike.

Power, when activated by a throttle on the handlebar (power-on-demand) or in response to your pedaling (ped-elec), gives you an immediate, nearly silent push. When you release the throttle (or stop pedaling), the motor coasts or “freewheels” – like when you stop pedaling a regular bike. Standard bicycle hand brakes and gearing round out the controls.

First off, distinguish between the bicycle and the drive system. If you’re having problems with a bike part, your local bike shop can help. Or you can find lots of useful fix-it information at Sheldon Brown’s website: www.sheldonbrown.com , get Bicycling Magazine’s manual at: www.bicycling.com , or get an interactive repair CD from: www.bfr-it.com (1-866-237-2453 toll free).

If the problem is electrical, you can call or contact us. Most electrical parts are subject to our warranty which means full replacement.

How Electric Bikes Perform Depends On Many Factors. The most important factors are listed here with the (generally speaking) most important at the top:

1. battery capacity (measured in volt-amp-hours)
2. terrain (number and incline of hills)
3. e-bike speed
4. wind conditions (going 10 mph against a 10 mph headwind feels like 20 mph to the bike)
5. pulling a trailer (which is like pulling another bicycle)
6. correct tire inflation (under-inflated tires slow you down)
7. weight of rider and baggage
8. motor/controller/drive system efficiency

As you can see, battery size ranks at the top. System efficiency ranks at the bottom because most systems are 85% to 95% efficient. The speed you go makes a big difference in how far you go. All else being equal, range is a function of either 1) battery capacity (amp-hours X volts) or 2) speed. There is a direct relationship between battery capacity (amp-hrs) and both weight and physical size (total volume). Commonly used sealed lead-acid batteries weigh three times as much a Nickel Metal batteries of the same rating and four time a Lithium Polymer battery. All else being equal, speed is a function of motor (watt rating) and controller. Most electric bike motors are capable of higher performance characteristics than the controller allows. As for power, consider that Lance Armstrong’s average speed over a 2-hour ride is 20.5 mph. Lance expended about 1/2 horsepower, or 373 watts, continuously. Most e-bike motors operate continuously in the range of 300 – 600 watts. Most e-bikes, therefore, will make a “Lance Armstrong” of difference in getting you down the road and up the hill!

Regenerative braking doesn’t yield much “juice” back into the battery. Even the hi-tech regen on electric automobiles gains less than 10% of the original charge. Therefore, given a choice of either regen or freewheeling, you will generally get more range with freewheeling – unless you have a hilly route.

Due to the nature of batteries, you can double the battery life expectancy by discharging only 50% of capacity instead of 75%; you get 6 times the battery life at 30% capacity usage per cycle. Think of battery lifetime as having $1000 in the bank and withdrawing a dollar with each 30% discharge cycle — and withdrawing $10 every time you deeply (85%) discharge the battery.

All Revolve products come equipped with one of two different types of batteries: lead acid, and lithium. Each type has direct attributes and characteristics, and is designed for different purposes. See the individual descriptions below for an overview.

Lead Acid: This battery is the same as your car battery. These batteries are quite heavy (25-30 pounds), but also very inexpensive. Lead acid batteries have an expected life of approximately 300 recharges.

Lithium: These batteries are in many ways the opposite of lead acid batteries. They last approximately 600 recharges, weigh around 8 to 10 pounds, but are more expensive.

All batteries are designed for use with their specific bike, so that there is not extreme variation in the maximum range that our bikes can travel on a single charge.

Revolve stands firmly behind their e-bikes with a 6 months warranty on the bike frame and components, and 6 months on its battery and motor (excluding normal wear and tear, misuse or damage). Find out more about our warranty here.
