High Torque is needed for steep hill climbs and be aware of your motor speed - a low RPM motor generating a lot of torque takes lots of battery power. That's why mid-drive bikes are better for hills - you can shift to first gear - spin up hill with a faster motor RPM and lower Wattage. Display read 300W Mid-drive vs 850W Hub going up same hill. Of course I was pedaling, didn't want to overheat motors. I installed a Bafang BBS02 mid-drive on a MTB and sweet ride. @ 40 lbs and fast. Usually keep the bike in 2nd or 3rd gear so easier on motor controller, got mine from Luna Cycle @ $450. I've done the Cheap Chinese Hubs and they're good if you just want to go cheap and do a lot of throttle. Nice on flats but battery killers on hills. Pay $250 more for a mid-drive kit - it's a better e-bike in the long run. Look at a Tong Sheng TSDZ 2 mid-drive (80 NM @ $400 shipped, torque sensing pedals ) Open source software improves performance so it's like a Bosch - excellent commuter, torque sensing applies power when needed so longer range. If you want a lot of power - BBSHD - 160 NM @ $800 - the Base motor is excellent for Upgrades. Check out "Andy Kirby" e-bike channel if you want to go really fast. For me BBS02 - 120 NM @ $450, great bang for the buck.

High Torque but low HP= A guy (motor) with a lot of brute strength but who can't run very fast. He's got the brute strength to easily run uphill with a heavy backpack but can't run super fast with or without the heavy backpack. High Horse Power but low torque= A guy (motor) who doesn't have the brute strength but who can run much faster once he gets going. He can run really fast once he gets going but it takes him longer to reach his top speed and he can't carry a heavy backpack.. Big strong football linebacker= Lots of torque but slow, can't run fast (low HP)... Slim fast running wide receiver=More horsepower than a linebacker so he can run faster but doesn't have the brute strength (low torque) that a line backer has.

Note, a 250w mid drive motor can climb better than a 750w hub drive motor in certain situations because is uses the gears to increase torque at the wheel. So when the hill gets too steep for the hub motors torque which is fixed the bike bogs down and stops, but the mid drive uses a lower gear ( slower speed) to swap speed for torque and can climb the hill still. Personally I'm happy to just have a powerful enough rest hub drive to go up most hills and I pedal hard on the steeper ones.

@MHH3180 2 жыл бұрын

I build only torque sensing mid-drives for my customers, but everything discussed here really means little. Even a junk bike, with a low power, low torque motor is still a ball to ride and probably all most people will ever actually need or use. I spoke to two of my customers yesterday that never get out of level one of five assist and they put in some pretty impressive miles.

@@MHH3180 I agree most people will never use the higher end bikes to anywhere near their potential. I now have a Frey ex which uses bafang ultra so I can directly compare it with a cheap 1000w dd rear hub on a cheap full sus bike. For 90% of the riding I do which is mild off road the hub is faster and easier to ride. I literally have to go looking for harder trails to even start to test the capability of the ultra motor and the high end bike and it scares me tbh just how steep you have to get to get your money's worth lol. I'm thinking a tosheng on a cheap bike would be perfectly ok for most people.

@MHH3180 2 жыл бұрын

@@FlyingFun. yes, I have built approximately 75 bikes using The TSDZ2. All mine have to be legal everywhere. I use the 48 volt 500 watt as it is capable of 52/750 and the torque sensor means even the most feeble of grannies do not need a throttle. All that pretty much eliminates all my warrenty issues. I did have the world's third strongest man break a spindle I should have realized was loose and just this week I got a bad display from the distributor. I have had two former motorcycle riders complain their 700c hybrids don't accelerate like theor 20" folding 750 hub motored bikes, but I thunk cadence sensing appeals more to anyone looking to do as little pedaling as possible. Really though, I am finding a lot of my customers would do as well with something like The Retrospec Rev line. They aren't going to go great distances and the savings could buy a lot of extra batteries. The speed limit on rail trails, MUP's an in the bike lanes they ride is 15mph. They don't mind climbing hills a little slower. If they ever perfect puncture free tires, I may have to hang up my smock.

@@MHH3180 yes if building for paying customers I would 100% go tosheng for the reasons you state. I've had a few people ask me to build them a similar build to mine with 1000w dd rear hub but I'm really reluctant because of the need for torque arms correctly installed being slightly different on every bike and the legal side of things so I passed but said I would help them do it if they wanted.

@super73uk 3 жыл бұрын

Hey Buddy, Great video as always! 👍 👍 Agreed that the bike with more "power" would win the race BUT only if; 1. The race was not up a hill that was too steep for the bike with more power (and not too steep for the bike with more torque). 2. The distance of the race was such that there was enough time for the bike with more power to catch up with the bike that had more torque. So if you live in London or New York for example and use the bike mainly in the city then because of all the stopping & starting (traffic lights & T junctions etc) and short runs, having decent torque on a bike would make a lot more sense that having poor torque and a few mph extra top speed. We are not trying to be clever or funny, we are just trying to point out to other people that having a bike with say 2000w "Peak power" and "low torque" is not always better than having a bike with say only 1500w "peak power" and "high torque" if the bike with 1500w has a much better torque curve and you are using the bike around town or in a hilly area on a regular basis. We wonder if some manufacturers just go for the higher power motor figures because a lot of people would look at the figures and assume that the bike with the highest power rating MUST be the best bike to get when in point of fact it really all depends on what you want from the bike in terms of performance and also where and for what you intend using the bike. Thanks again for all that you do for the ebike community - You are "Top man" 👊 😎 👊

@james-p Жыл бұрын

That's the first thing I noticed too. As you noted, you could put those two bikes on a hill, let's say a hill that is very steep - just steep enough to where the 25 N/M motor can't get the bike moving. The 50 N/M bike would win, just because it has enough torque to get going. It's the same reason that a 100 horsepower 750cc motorcycle engine would work badly in a car. Lots of power (because of high RPM), but much less torque than a 2 liter 100 horsepower (because of slower RPM) car engine.

You make a good point - Totally agree with you! This is the reason a lot of people want more torque than what you get as standard on the Super73 bikes. Great bikes but poor torque. Thanks for your reply & best wishes.

Exactly. As someone who lives in a hilly area, I am all about the torque. The street I live on is steep and my driveway even steeper. I have two bikes with 95nm of torque, one hub and one mid drive. The hub drive is 750W and the mid drive is 400W. Neither one will make it up my street, much less my driveway, without significant pedal input and it takes about the same time and effort to climb the hill between the bikes.

Love your bike in the background by the way, I just got the same bike in the same color 2 weeks ago!...I just recently started watching ebike stuff on KZfaq and had no idea about your giveaway but what an awesome idea. My bike was a reward to myself and a way of getting an important part of my life back. Last summer I entered a rehabilitation treatment program for alcoholism and lived for 4 months in a supervised environment with 12 other guys. It was tough but I did it and now I'm in a transitional housing program at the same place but have my own apartment. Before life got out of control on me I used to cycle alot and that got forgotten about completely when my misguided priorities changed. Now that I've been sober more than 9 months I bought the radmission to get back into riding and decided to go with an ebike as over the last 5 years or so I did an amazing amount of damage in general to myself. Riding any distance without the assistance just isn't happening and with the pure joy of getting back out and getting exercise I can slowly rebuild my body. That bike really is life changing for me....just curious about what kind of radbikes you gave away?
