I can keep my dirt bikes running for ever. My 1971 Trail 70 works every spring. But an e-bikes are going to have a short life span. A 5-year warranty is pretty good. You just have to accept that’s the lifespan I think.
I’ve loved the fezzari e-bike I bought. Even if it only last 5 years before it’s not worth anything I think I’ll be happy.
My dirt bikes end up just sitting in the garage while I can ride my e-bike daily from my house to the trail. Could….. being the key word.
