How heavy are eBikes and does weight matter?

Most eBikes weigh 40-70 lbs, compared to 20-30 lbs for a standard bike. Weight matters most when carrying the bike (stairs, transit, loading a car), when riding without motor assist (dead battery), and slightly affects handling agility. The motor compensates for the weight while riding — you won't notice the extra 30 lbs while pedaling with assist, but you will when carrying it.
