hi....do this pedal assist system add your effort in moving the cycle or just sense your effort and provide input(for motor) accordingly.i mean it synchronize your effort with motor or the motor is the only source of power?

Depends on the level of assist you dial in. With some systems, the sensor will provide full power with the most minimal pedaling or you can dial a degree where you're providing most of the power. I have a BBS02 system that's used offroad with a 52V, 6 ah battery, and use either no assist or level 1 (of 5) 98% of the time.

My commute is 18 miles each way. I/d been doing it for about 10 yrs on a regular bike 3 days a week out of 5. I bought a Raleigh Lore with pedal assist and torque sensor. I love it. I've ridden into work every day since I bought it, the commute is FUN. I've put on almost 700 miles in the past couple of weeks. I appreciate that the Pedal assist makes you work a bit and enjoy the workout without being crushed by it. I see many folks riding the throttle powered bikes....they look bored.

I've a friction drive kit coming and the manufacturer shows power usage for 3 modes: PAS, "tailwind", and throttle. Tailwind means the motor comes on after one achieves 8mph, with 3 levels. The most power hungry is the PAS (because it is on all the time), second is tailwind, and least battery usage is throttle (assuming one is being judicious and not using it on flats). Having the choice of all three (or two, PAS & throttle) seems like the best option. Riding by myself I'd use throttle only when I really need it. Riding with my son I would use PAS as he hates waiting for me. Tailwind would be for days when I'm pooped out and heading back and the bay winds kick up. The other nice thing about a throttle is if you ride in traffic you can use it to clear intersections quickly. Each has a purpose and to me the ideal bike/kit has more than one option.

I use PAS 99% of the time. The only time I use throttle is to get the bike going from a stop. Most electric bikes are pretty heavy and just don't make sense to pedal without it. Holding the throttle at a constant position while you ride is a pain.

That's what I like about the thumb throttle on my DD conversion. It's positioned so my left hand on the grip keeps it actuated when riding on long stretches.

The BionX system (RIP ) seamlessly senses the rider's effort and synchronizes it with the motor. The torque sensor feels the amount of tug on the chain. The more the tug the more the assist at whatever level you have chosen.

I only installed my throttle once briefly then removed it. Not designed for drop bars anyway. If I need to start fast from a stop I just put it in level 4 assist and apply light pressure to the gas pedal. The bike then shoots ahead as if it had a motor!

Using a throttle is tiring. Its fine as a booster, which is why i have one. But the pedal assist makes the bike fully automatic, and is what makes it a power assisted bike.

You dont have to ride no-handed, you may not agree with it, but the fact i can ride no-handed up steep hills shows how a pas does its job. You simply forget about the electric, you dont operate it, you simply habe the wind in your sails.
