Purists reckon they are for cheaters, but an electrical mountain bike can easily turn a bike trip round and make it much more exciting and enduring.
For me, I really like the feeling that you get taking a bike down a hill at speed; the tough slog to get up on the other side is a struggle (good - I enjoy challenges!) But it can wear a little as the hours move on.

There are a couple of precautions you can take to prevent water damage.
An electric mountain bicycle has four main components which have to be shielded; the motor, the battery, the controller as well as also the connecting leads. These should all be waterproofed somehow, either from the factory that created it, or by DIY means.
If you wrap some of the elements in vinyl (silicon or electrical tape works well) to preserve the components without obstructing the moving components or preventing you from getting in the parts should you need to check it over. The watertight coating will keep everyday damp out.
