Awesome hunt @thesky. Here are my reviews;

Pros;

• Good for Urban Areas
• Healthier Than A Motorbike
• Pedalling Still Required
  The Køben use an ePAS (Electic Pedal Assist System) system. Put simply, you pedal your bike normally but when you need a bit of a boost the onboard computer engages a motor in the crank to make turning the pedal much easier.
• Range
  With most fully charged Køben the assisted range is over 20 miles on a single charge.
• Quick Charging Times
  With charging times as low as 4-5 hours, it is easy to recharge the e-bike during the working day so it is ready for your ride home.
• Availability
  The great thing is that all types of bike and models are available as an e-bike.
• Weight
  One of the attractions of a conventional bike is that it is fairly light and easily transportable.

Cons;

• Price
  Although much cheaper than a car or motorbike, they can be more expensive than a conventional bike.
• Legal Speed Limit
  In order to stay within the requirements of the vehicle that doesn’t require tax, insurance and a licence, an e-bike has to remain limited to speeds under 15.5mph while being powered by electricity.
• Maintenance Costs
• Every vehicle must be maintained in some way and the e-bike is no different.
• Short Distances Only
  Finally, although the e-bike is likely to be popular amongst urban users, those who have to travel within rural areas or commute for long distances need to be mindful of the range of assisted pedals and plan their uses of power carefully.
