Don’t Go for Surplus or Cheap Electric Bikes

A lot of cheap electric bikes are not 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 fat tire bikes lack even the most basic electrical safety features, which can put 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.
