Rad Power Bikes says that starting July 1st, prices on some of its models will increase $100-$200 due to the recent expiration of the tariff exemption for Chinese-made e-bike batteries. In a letter to customers, Rad Power CEO Phil Molyneux said the company was committed to affordability and would continue to offer free shipping in the US and free two-year warranties on every e-bike purchase. Still, this is just the first indication of what is likely to become an industry-wide problem soon enough.
