How Long Do E-bikes Last?

      One of the best features is that they remain useful for a long time. They are very durable, and they are built to be safe. If they are maintained well, they can last for many years.

      No matter how expensive and high-tech electric bikes are, they still rely on the main power source – a battery. The only way to ensure the battery will make it through long journeys is to have a trusty charger to help out.

      Another question many people ask is “Can you still cycle without the battery”?

      And yes, it is possible to ride without the battery when it has lost its charge without causing any damage to the motor. The battery is only there to help riders with the pedal assists or in other cases the throttle when it is needed.

Are E-bikes Safe?

     The short answer is yes, they are safer than regular bicycles due to how they are designed.

     They utilize an in-line electric motor powered by a battery, which takes the place of the traditional pedalling, and this makes them very safe to ride on the road, and ultimately gives you even more control.

      A study from Portland University found that 60% of owners felt safer riding an electric bike and 42% of riders felt they had helped them avoid accidents.

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.
