    The people who don't understand it likely haven't tried a 72v bbshd. Once you do you get why many ditch all the gears for a single speed. I kept mine because I do like to do low wattage pas on my rides, so this means I can keep up with the pedals and actually input something, but when I'm using the throttle 90% of the time I only use one gear. One of the good things is 72v opens up the choice to go single speed if it suits your riding and needs, try that on 52 and it likely just will not work out well.

    I use BBS02 + 3 speed Shimano Nexus IGH on 18 amps and 48 volts. I do that because I don't need that much power. This saves my controller, battery, and motor. 1 gear is for up to 22 km/h, 2 strongest gear (1:1 ratio) is for up to 32 km/h, and 3 gear is for up to 40 km/h. I stay mostly at 2 gear. 3th gear allows me to pedal up to 25 km/h. There is no problem with chainline, alignment, or maintenance. I understand your setup, but for me, it is a little expensive with this new controller and larger motor. In the USA, IGH hubs are less common, but here in Europe, all middrive factory bikes usually come with IGH. Still your setup make some sence. :)

      I was looking at that Shimano Nexus Inter3 , i wonder if it can handle lots of power? Maybe in the 1:1 gear? It would be nice for pedaling.

      ​ @EBikeBuilder_ I know a guy with a 52-volt BBSHD and a Nexus 3 who has no problems. 5 speed is ok; 7 speed is a big no; 8 speed is ok. I previously used a 7-speed SRAM spectro s7 on a mountain bike, which was excellent for lite trails, asphalt, and pedaling but heavy shifting up, and more maintenance.

    Does single rear chainring use an adapter ?
    And please do video about internal cooling upgrades 👍

    • @EBikeBuilder_
      @EBikeBuilder_  7 หลายเดือนก่อน +3

      Pinion P8200 is the adapter yeah , it allows you to use 104BCD chainrings on the cassette splines. I will do a video about cooling i need to figure that out cuz the BBSHD gets hot baby!!

    What’s the matter with both worlds! I’ve been riding my High Voltage bike in Florida for the last week with 20+miles of pedaling using my gears and very little watts (65-200w) with no issues with chain skip,shifting or loss of chain on a 10 speed cassette. Granted I moved one small sprocket inside of the large sprocket for a better chain line so big deal I’m down to 9 speed. I find myself 10 miles from home or more with close to full battery and just throttle home at 40+mph with no issues. The motor never got any hotter than 110 degrees and was just warm to the touch in 80 degree weather. I love your setup and what your doing but I love having the ability to go do some single track riding in deep woods while pedaling at lower wattage and the ability to just rip home after. Im not trying to disagree with you but the bbshd at high voltage can be so much more with the right bike

      I could use a shifter and have the cassette and whatnot if i want. I’ve thought about having one wheel with this set up. And one wheel with a cassette. And i could just switch them out. It’s whatever you want it to be, really. I like not having the motor in the wheel A LOT !!!

      In this video i was just trying to explain to people why and how the single speed BBSHD works , when its on a higher voltage and field weakening, there’s no need to shift and there are other possibilities. Just need to keep an eye on the heat. it can be used as designed also, just need to turn the power down. I’ve always thought BBS02 felt better to pedal personally. I want to try with 72V and the phaserunner. if I’m pedaling along with the bike i like the Q factor of the 02 and better RPM for human pedal cadence. BBS02 could be fun on 72V I might try it

      Totally get what you’re saying. I have a carbon fiber aero road bike and pedaling it is super smooth with electronic shifting and even with power assist on my mountain bike pedaling can be a bit of a challenge mostly I think because of the bounce in my full suspension. Honestly I can pedal it with absolutely no power on at all and it’s not bad but once I add about 70w it rides pretty nice. Not perfect since I often tap on the throttle up hills since it’s only cadence based. I just know I like to have pedal options and full 4000w when I want. I’ll be down in FL for another month and a half so I will be riding just about every day. Hopefully find some great new trails before I head back to IL.

      @@kmtnbike1117 that’s a good point about adding just a little power for pedaling it, i think with the way i have virtual freewheeling set up on mine, you could adjust that until it felt good for pedaling.

  • @bassw1758
    @bassw1758 7 หลายเดือนก่อน +2

    What if? Instead you go with a 17t and help paddle it up to 20mph ish? And help it on the hills up to 30mph? I think your top speed would be off the chart

    • @EBikeBuilder_
      @EBikeBuilder_  7 หลายเดือนก่อน +4

      the fun for me is its such a light bike and its crazy torque , i just gear it as low as I can for the most torque, while still being able to have a decent top speed of like 40MPH or whatever you need. I geared it higher 46T:32 and its more of a 40MPH cruiser that way. But the torque is fun. Whereas my top speed I only maintain for like 1% of my bike rides. So with this bike its kind of prioritizing torque because tahts always useful for 99% of my rides.

    Can I use any generic aftermarket controller to achieve the higher RPMs? And does it require 72 volts to do this? I'm ok with the power levels achieved at 52 volts and I already have a battery. Thanks!

    • @NoHesiBMW

      You can get a higher amp controller however 72v will get you higher wattage at lower amps as watts=voltsXamps

    • @EBikeBuilder_
      @EBikeBuilder_  6 วันที่ผ่านมา

      you need a controller with field weakening to do the higher rpms, and also to gear the bike lower than usual, then it can really fly, but dont try that on 52V, i dont really recommend field weakening on 52V, it gets too hot

  • @bassw1758

    What would be the outcome be against a hub motor of the same wattage you think?

    • @EBikeBuilder_
      @EBikeBuilder_  7 หลายเดือนก่อน +2

      at 90A phase current with 46T:42T gearing, the 72V bbshd is about 260nm torque, its very torquey , gets going up to 30 very fast. On flat and even up a slight incline, it can maintain a good 40+ mph with this gearing. I think the hub motors kind of mitigate heat better though. its easy to get the BBSHD hot.

    • @EBikeBuilder_
      @EBikeBuilder_  7 หลายเดือนก่อน +1

      When my g62 is going 30+ MPH, it feels a little more torquey than this bike. but at lower speeds and 0 to 30 and stuff the BBSHD is way more torquey, even with lots of field weakening. And trail riding, the 72v bbshd is gnarly. Turn off the field weakening, for max torque , it would absolutely rip. I think i could probably ride this bike in the trails OK i will have to try it. With some different tires. When things dry up a bit. The mid drive definitely feels more nimble and balanced in terms of weight. Its nice not having the motor in the wheel

    Sick riding crocs! =p I just wanted to comment that @4:49 you come up to an SUV pulling out of a parking lot then hope and pray it doesn't pull out in front of you. This is something I see so many ebike youtubers do and it's so so unsafe. Practicing defensive riding is very important more so than on any other type of vehicle. The safer thing to do in that situation is pull across to the inward side of the lane and preload your front brakes a little bit. That way if the SUV does pull out in front of you your brakes won't unsteady you if you pull them too hard, and you have as much space as possible to maneuver around the car. Please always ride with the assumption that cars do not see you, our bodies are too fragile to account for the mistakes of others.
    Stay safe brother o7
