MOTAN M-B2 Fat Tire e-bike has TWO batteries and is similar in style to M-550, but the M-B2 is more powerful with a Bafang 750W motor. With the double battery capacity, it can afford twice the range of 80-100 miles. The dual battery technology makes the M-B2 unbeatable when it comes to long-range and ascent. The M-B2 has a sturdy 6061 Aluminum-Alloy Frame and has four inch wide fat tires good for on the road or on the beach*.

While riding, priority will use the downward oblique tube 17.5 Ah battery. The system automatically switches to the upper tube 10.5Ah battery in 0.5s when it detects a charge difference of five percent. The batteries can be used separately. If necessary, bikers also have the option to use one of them. Both batteries can be charged on the bike at the same time or charged separately on an external charger. It comes with one charger that can be used to charge the two batteries, whether mounted or removed. Starting from a completely discharged state, the charging time for both batteries is 11 hours, or 7 hours for the 17.5Ah battery, 4 hours for the 10.5Ah battery.

With the dual battery technology, day tours over 80 miles are possible. So you can focus entirely on riding, without constantly being preoccupied with range. For short trips or in day-to-day use, practical technology requires significantly less frequent charging cycles. Therefore, the dual battery technology is an amazing solution not only for touring bikers but also for daily commuters.
