It says I burn 450 calories a day for 28,7 km. So when I ordered the bike, I started going to work with a manual bike just to get used to it.

The difference is clear. My knees hurt for 2 weeks, my quads were lightly sore the whole time. When I arrived, my back would be wet from sweat.

But I would be a lot slower, I'd be taking a lot of breaks between pedalling. The hills would take a lot of energy, like it's a squatting set.

When doing cardio, it's important to be consistent.

The bike I'm using, never tried any other e-bike, is the R&M Multicharger2 GT Rohloff.

I'm always on the automatic mode. With the system that it has, it adjusts how much power it assists with.

The bike weighs like 30 kg.

Going up hill is very easy, it automatically shifts to a lot of assistance. Then it stops doing so.

Braking doesn't feel like a pain in the ass anymore, so it's a lot safer for pedestrians. On a manual bike you'd hate braking because getting started is a huge waste of energy. With this thing, you just shoot ahead quickly and then it stops assisting until you get in higher gears.

You can handle the bike quite well, as you can use your pedalling to adjust the speed. You can easily go at walking speed and you easily can go to max assisted speed or in-between.

It's a lot easier to choose your own speed than my wife's la souris scooter.

For the burning calories part, I asked yesterday le chat mistral why. It said that because it helps you stay at top speed for the whole ride, you take no breaks, it just keeps you consistently into the same burning mode.

I often go at 26 to 29 km per hour. It only assists to 25 km per hour. If it's a flat road, it will minimally assist. The bike is 30 kg, I'm 90 kg. It's still a good workout. When I get tired, I can keep pedalling, I just go to 25 km per hour at minimal assistance. Until I can go faster again.

With a manual bike I would have to really just lower the gears and rest up for a while, dramatically lowering my intensity and speed.

Hope this helps
