The bike is the most stolen in the world, hurt by the loss, the route of 25 km and all climb ..... a record time, the descent has been easy,A cyclist must control his heart effort with respect to his age and think about what that means to the cyclists of the older group .... not counting if they take any medications that can have negative effects, know the weather and be prepared For the most adverse of the moment because 10 degrees celsius to 25km imply a freezing thermal sensation, stop on your route to drink, eat and regain strength.Good ebike.Congratulations
