Electric Bike History

       The very first electric bicycles were documented in the 1880s and 1890s in the patent offices in both France and the United States. In France, one of the earliest was a three-wheeled electric contraption, the motor power controlled with a hand-held lever system without any pedals.

        In 1989, the first ‘Pedelec’ or Pedal Electric Cycle (now referred to as pedal-assist) was created. Rather than using a throttle mechanism to control the motor, as all previous models had, pedal-assist allowed riders to utilize an electric bike not so dissimilar to how one would ride a regular bike.

       Today, the use of electric bicycles worldwide is steadily rising. Their availability and mobility have not only made biking more accessible but has also elevated the sport to levels previously unimaginable with bicycling now a choice for riders new or old, whether they are on roads high in elevation or leisurely cruising city streets.

Saving Money!

      Anyone can see the massive cost disparity between a car and an electric bike. Motor vehicles have been the preferred method of transport for millions of Americans for the last 100 years. They're massive, go from zero to sixty in seconds and fly around mountain curves with ease.

      All that power tends to cost a lot, though it is certainly possible to find a motor vehicle for a few thousand dollars, high-end models push into six figures or even millions. Constantly filling the tank with expensive gasoline adds up costs fast as well. Electric bikes cost a fraction to purchase, pennies to charge, require minimal maintenance, and no expensive insurance! For these reasons, the more cost-friendly — yet still classy and cool — electric bicycle offers an attractive alternative.

      It's also true that when a motor vehicle breaks down the repairs can cost much more than an electric bike repair. Preventative maintenance on a motorcycle or a car is usually more expensive than the maintenance an electric bike requires.

What is an electric bike or e-bike?

        An e-bicycle is one with an electric motor (attached to the bottom bracket or front wheel) that assists the rider with their pedalling.This means that while you’re still getting a workout – and enjoying the scenery – you don’t need to pedal nearly as hard, especially up hills.Under UK regulations, e-bikes – or ‘pedelecs’ – cut the power assistance when you stop pedalling or when your speed reaches 15.5mph.

        E bikes use rechargeable batteries and typically travel up to 25 to 32 km/h (16 to 20 mph). High-powered varieties can often travel more than 45 km/h (28 mph). they are gaining in popularity and taking some market share away from conventional bicycles.

        How the electric bike motor gets the power to the wheel falls into 4 basic classes. Friction drive, mid drive, left side drive, and hub motor drive. Friction drive uses the motor to rub the tire, pushing the tire by friction. As you can imagine, a bit of water or mud on a tire could affect this method. Mid drive means the motor is mounted in the middle of the bike, near the pedals. Then the motor connects to the pedals, so the motor actually helps the rider pull the chain on the bike. Mid drives work great, when the rider chooses the right gear. Choosing too high a gear can result in lots of chain and gear wear, and in some cases actually harm the motor or the battery. So with a mid-drive bike, you have to think about which gear to use at all times. Left side drive means a motor uses the left side of the rear wheel to transfer the power. It might be an additional chain and sprocket on the left, or it might be made so a rotating disc pushes on the spokes on the left side of the wheel. The main drawback of left side drive is noise. Most are very loud, with the extra chain and sprocket. The simplest and most elegant solution is the hub motor. With the hub motor, the motor is actually located right inside the hub of the wheel. This makes it easy for the novice to install on a bike, and the result is a quiet ride that is never in the wrong gear. In fact, many users of a hub motor put the bike in one of the higher gears, and never need to shift gears ever again.
