This person keeps blathering this BS. <snip!>
Not even a little surprised we are seeing this combo of vitriol and misinformation again.
That stuff about 48-50-tooth rear sprockets and no torque advantage is profoundly wrong, and extremely bad advice to give to someone asking for help on how to spend their hard-earned money.
We can make this simple for anyone to understand, without regard to mechanical experience or inclination, with this simple test:
Forget about motors. Just sit on a bike with a derailleur and a rear cluster. You don't need a hill. Start riding. Shift to a bigger cog. It gets easier to make the wheel go around. Shift to a smaller cog. It gets more difficult to make the wheel go around. Forget about everything else (the gearing's effect on speed, hill or flat ground etc.). Small cogs and slight difference? The principle holds. Big cogs and small difference? Big cogs and big difference? It doesn't matter. This is how gears work. Big cog easy. Small cog hard.
Fast forward to an ebike. The mid drive motor is you, now. It rotates the chainring, which moves the chain, which rotates the cog which turns the wheel - just like you do, but stronger. Big cog easy. Small cog hard. Just like it is for you. Except if you are a hub motor you get only one gear and you have to suffer thru that. Try riding up that hill without shifting gears, which is what a hub motor has to do. Was that fun? Of course not. Does the hub motor have huge power that can overcome this inherent disadvantage? read the spec sheet. Nope. Even the little BBS02 has 120 Nm. The Bosch Cargo motors have I think 85Nm. The best fat hub on the market has 80 or 85. So... mechanical disadvantage and no extra power to make up for it.
If we're on flat ground, the differences go away. But thats not what the original poster asked about. They need to deal with hills.
@indianajo you are welcome to whatever opinions you care to have, but at least try and have some decency about how you conduct yourself when dealing with others who need help. This is a forum to help people and give advice. You are costing people money and creating real suffering if someone has a need, a budget and learns the hard way how wrong you are. I'm sure you have things to contribute here that are valuable and worthwhile. What you are doing here is the opposite of that.
Also: Cargo Bike Republic is a community with almost 14,000 members. All cargo bikers. Not just a couple of opinionated, self-important cranks. Its unfortunate to have to mention this, but if someone wants to verify who knows what they are talking about outside these walls, you can go to a place where literally thousands of people who know this kind of bike and lifestyle inside and out are happy to help give advice and clear up misconceptions.
