For under $1,000 today, you can buy a surprisingly capable e-bike that can reach 28 mph (45 km/h) and with at least 20-30 miles (30-50 km) of range. In fact, the single best-selling e-bike in the US is priced at $999, and it’s a darn good one! Spend a little more – say $1,500 to $2,500 – and you can get a genuinely excellent commuter e-bike that can easily replace a large percentage of daily car trips, and that you can count on for years and years of use.

There is some great information here about using a bike, especially an ebike, for more errands. I can tell you that I no longer driver to the drug store, the dispensary, Home Depot, my primary care doc and, a 2 bag grocery order. And I live in one of the most bicycle hostile cities in Arizona!
