After having to put together a bulky special flat tire repair kit for out two Class II e-bikes with rear hub drives, with the replacement bikes I purposely chose Class III bikes with mid-drive and tire repairs on the road are no more difficult than with a regular non-bike. Where we ride we can be 30 miles or more from our vehicle and so we need to be able to repair a flat where it occurs and not back at the house. 30 miles would make for a long walk back to the car. Rear hub drive power trains are less expensive to manufacture but are not optimum for someone who wants a pedal assist that results in a bike feeling like a normal bike when riding. Our Creo Turbo SL provide that experience and are also the lightest e-bikes around at 27 lbs in total.
