I have a road bike and I need a transport to get to my current job. It's about 12 km from my flat but I have to go up two hills, one of them it's 1.5 km long. I woul like to know the most suitable ebike kit to a road bike, the range of the battery will be 25-30 kms, and I don't know what is the best option, hub engine in rear wheel, or hub engine in front wheel, or mid engine. I need a trusty ebike kit.
Please help me whit your tips and experiences.
Thank you for your time.
Most 1.5 km hills are engineered to a max of 7%, something like that. There are online tools and GPS trackers that can tell you. Most hubs can handle 7%

What bike? What's it made of? What brakes? Condition?
