A grid-charged battery that drives an electric motor can provide mechanical energy approximately ten times as efficiently as a person eating a normal diet. This is according to a systematic energy flow analysis. The best electric bike is the best option for personal travel, typically between 5-30 miles per day. It also has the lowest environmental impact and personal monetary cost.

This may seem obvious but it is the main advantage. An electric bike can flatten hills and reduce the groan factor caused by a gradient. With a little effort and a bit of luck, an electric bike can climb hills up to 10% (10%) with no difficulty. It can also clear gradients up to 1 in 7 (14%). The effect is extraordinary in hilly areas.
It seems unlikely, doesn’t it? The mathematics proves it is possible. Imagine a busy, steep road with 30 mph cars. You will see 33% fewer cars if you can climb the hill at 12mph and you'll be passing them at 18mph instead of 24mph. We think so.
No matter what the numbers, an electric bike can help you stay out of danger. Similar principles apply to road junctions: the faster you accelerate, the quicker you can escape from trouble. You won't feel the need to rush downhill, so you won’t be tempted to go at breakneck speed. Another safety feature.
