I recently had my third hybrid bike upgraded by Bike Swift. I obviously enjoy their product. I looked elsewhere for upgrades and Bike Swift offered a very simple and complete package. I also looked at buying a new E-Bike and tried all the name brand E-Bikes but none of them had one feature that I really value- Throttle assist which allows you to use the bike without pedaling. Bike shops refuse to sell the feature because the bike becomes something other than a bike (in their minds). But as a 69 year old man and with a partner who has lung disease, sometime the throttle is how we get home from longer rides. Also, if you become injured during a ride, the throttle assist will get you back as long as your bike isn't destroyed. Great product. Very happy with the results. I highly recommend Bike Swift.
