Don’t Go for Surplus or Cheap Electric Bikes!

Many cheap electric bikes are neither reliable nor safe, so buying one is often hit or miss. They are not designed for sustained use because of poor craftsmanship or poorly-done electronics. Some cheap electric bikes lack even the most basic electrical safety features, putting the user at risk of electric shocks. Also, a lot of surplus models cannot climb hills or provide enough level of pedal assist. They are equipped with cheap batteries and cannot go far. 

If something goes wrong, there is no way to have them serviced. You cannot depend on them. Lastly, most are not comfortable to use. Choose safety and real performance. Only choose electric bike brands that have years of presence in the market and have certifications. 

Eunorau Bikes: The International Electric Bike Brand

Electric bicycles are the way to go for an active and sustainable lifestyle. It has been proven that such vehicles allow people to achieve physical activity levels, especially those who are not fit enough for exercise. Newer models of electric big tire bikes are more powerful, with better components and motors, to bring them anywhere without worry about losing range. Driving a car in the city can eat up your limited time and cut productivity. Car maintenance, insurance, and gas are also costly.

Great bikes!

I purchased two e bikes, one for myself and one for my wife. We are still getting used to them but they are fantastic! We live in a very hilly neighborhood so that extra boost comes in handy. Mine has the front and rear motors and it has lots of power and torque. Enjoy!
