Hi folks. My wife and I just purchased our first e-bikes. We rented e-bikes in Niagara Falls and were instantly hooked. I’ve had 2 hip surgeries and am limited in pursuing the many activities in which that I was interested/active. Mine is a Gotrax Tundra and my wife has a Himiway Zebra. Both are step-thru frames. I was thinking of purchasing a second battery for both. Luckily both bikes use the same battery and would be interchangeable. I am worried that something will happen to the batteries and am considering purchasing a backup battery for both. Tariffs are on the horizon and I’m concerned that the price will become ridiculous. Any thoughts on our choice of bikes and purchase of another battery for each bike?
