Batería Original de 48V20Ah para Burchda RX80/RX50/AZ20

i am very happy with my E bike because it lets me continue cycling at age 77 even with 2 arthritic knees. i have a younger brother and we have cycled together now since he retired, over 10 years, on ordinary bikes he as always been stronger than me, but since my E bike i now cruise behind him no stress. 4 months ago he got an E bike from a local shop same price as mine but i still cruise behind him no stress. my bike a better range of speed and longer range of battery power, better lights, horn [not bell]. i recently purchased a second battery as i wanted to do longer solo rides, expensive but worth it to me. i then travelled 65 miles on number 3 speed, the bar lights showing power went out at 55 miles but i kept going to failure as i now had a spare, but another 10 miles and i was home. thus my panic in passed rides when down to 1 bar indicator was unnecessary. the only down side i have as been the rattling, i have removed mud guards, bike stand and still big bumps or holes and still a rattle. overall i could not be happier.
