On the Joy e-bike Glob, the battery spec is 60 V, 233 Ah NMC (lithium-ion) per Joy’s official site, delivering a claimed range of 60 km. The motor is a modest 250 W BLDC so it's not a speed demon, but practical for city commuting. I like its hydraulic suspension (telescopic fork+dual shocks) which cushions uneven roads well. The loading capacity is 140 kg, so it's quite usable for pillion rides too.
