Speaking of Liveforphysics, riding like a hooligan can quickly get you in trouble if you ride past police in a provocative manner. Manuevers such as the one pictured above should only be used off the road ways.   Use a lot of common sense. If you are moving fast it is a good idea to be pedaling fast so you appear like you are just an athletic bicycle rider.

  That is a lot of variety of e-bike rules, and we just looked at three states. Unless I am mistaken, New York still completely prohibits electric bike use on public roadways.  As you can see, it’s far too complicated and variable to be able to summarize e-bike laws for the entire USA.  Each state is quite different, in some you are a motor vehicle, and in some you are not. And even in one state, the power and speed your particular e-bike has can greatly change the legality of riding on public roadways.

Most consumers want an e-bike that will accommodate its motor without being too cumbersome and will remain stable in spite of its electronic components. Some consumers want only the most basic of e-bike features, including lights, a cargo rack/basket, and a water bottle holder. Others are focused more heavily on safety features, such as brake type. And still others are concerned with convenience and portability.

(*) Allowed on bike paths when electric systems are turned off (**) E-bikes are illegal in this region (***) Some regions have special regulations, see corresponding entry under Electric bicycle laws.

Weighing in under 15.5 kg (35 lb), with up to 1,000 watts of electric power, blind spot warning sensors, a GPS tracking security system and brand name componentry from stem to stern, Nireeka’s sexy carbon-framed electric bicycles appear to be a bargain for the price.

A lot of pedal assist bikes have different levels of assistance, for example: low, medium, or high assist.  Please note that some e-bikes have 4 or 5 pedal assist settings, but for this example we will just stick with low, medium, and high.

We sourced a custom spec 650 Watt geared hub motor that is not found on any other e-bike. The special high speed copper winding setup is intelligently driven by an upgraded 9-transistor controller peaking at 20 Amps.

Electric bikes (or Pedelecs) have been on the cycling scene for a few years already, however these have evolved from a necessity, which was primarily used for riders with health or fitness issues, into the new breed of serious off road bikes. All of our bikes are the pedal assist (not the throttle type) so some effort is required, the amount is up to you. Whether you’re looking to commute without getting too sweaty, to hitting the downhills with the power of an inbuilt uplift, there is a bike to suit your needs. Why own an e-bike?

Benny offers seamless integration of pedal assist making it the perfect e-bike for both first-time owners or experienced cyclists.   Smooth acceleration at your fingertips with the large LCD control panel.  A Powerful 750-watt motor is powered by either a 264wh/380wh lithium-ion battery.  The Benny is designed to be the go-to e-bike for hilly commutes and leisurely rides around town.

[…] e-bikes started appearing and so the NYPD treated any e-bike as illegal regardless if it was a pedal-assist or throttle e-bike. In recent years, the NYPD has been largely ignoring pedal-assist e-bikes while targeting […]

TerraTrikes make great electric recumbent trikes. Here are a few how to tips for converting the Rover and Rambler models, specifically with internally geared hubs. The TerraTrike Rover and the rambler models both are offered with internally geared hubs. It is possible to convert the trike to external gearing, but you will probably want the help of a bike shop that is familiar with recumbents. For a good bike shop,…

You ARE allowed to ride an e-bike in Texas faster than 20-MPH if you pedal up that speed.  So when you are going fast and see a cop, pedal as fast as you can.  We call it clown pedaling. Looks really clownish if you happen to be going 40-MPH. Don’t expect a cop to be fooled if your e-bike really goes 40-MPH…but sometimes cops can surprise you.

Around 90% of electric bikes are powered by standard lithium-ion batteries, but there have been further developments in the technology. These developments include lithium-ion polymer batteries, lithium manganese batteries, and lithium cobalt batteries.

H. “motor vehicle” means every vehicle that is self-propelled and every vehicle that is propelled by electric power obtained from batteries or from overhead trolley wires, but not operated upon rails; but for the purposes of the Mandatory Financial Responsibility Act [66-5-201 NMSA 1978], “motor vehicle” does not include “special mobile equipment”;

Do you love vintage motorcycles? Then we have the e-bike for you! The Italjet Ascot is a gorgeously classy model, with retro-chic styling that includes leather handlebar tape, a built-in storage bag, and brown bubble tires. Still not enough glamour for you? A gold chain completes the package. Naturally, it has a leather Brooks Flyer saddle, too. Even the lights look vintage, but nothing about how this bike handles makes it feel old. It can get up to 15 miles per hour with the help of the battery—the rest is all your leg power. If you always wanted a Vespa but couldn’t justify a full-blown scooter, this is one step cooler.

 Looks pretty similar to the Texas definitions, but there is one key difference.  There is no definition for electric bike. There seems to be no such thing as an electric bike in New Mexico. The closest match is “moped” So it looks like in the State of New Mexico the example e-bike is a moped.  Some good news, you can go 30 mph. And you don’t need to register and insure a moped.

In a friction drive motor, a small, solid wheel rotates against the side of the tire in order to drive it. The first motorcycles used the same concept, with a motor mounted above the front wheel. The problem is that the drive rubs at the side of the tire. It’s inefficient, and it quickly wears the sidewall away. Tires need to be replaced every couple hundred miles. For this reason, you’ll seldom see electric bikes with this type of drive anymore.

Another type of electric assist motor, often referred to as the mid-drive system, is increasing in popularity. With this system, the electric motor is not built into the wheel but is usually mounted near (often under) the bottom bracket shell. In more typical configurations, a cog or wheel on the motor drives a belt or chain that engages with a pulley or sprocket fixed to one of the arms of the bicycle’s crankset. Thus the propulsion is provided at the pedals rather than at the wheel, being eventually applied to the wheel via the bicycle’s standard drive train. An electric mid-drive combined with a hub gear at the back hub may require care due to the lack of a clutch mechanism to soften the shock to the gears at the moment of re-engagement. A stepless / coninuous ratio gear hub or a fully automatic gear hub may reduce the chocks due to the viscosity of oils used for liquid coupling instead of the mechanical couplings of the conventional gear hubs.
