    The other big change was reprogramming the controller which has made a massive difference to the way power is applied, making the bike much nicer to ride and easier to control. If anyone wants more details, drop me a line.

      @@marcostirado5537 I've been running this with a Rohloff 500/14 for nearly a year now with no problems whatsoever.
      I do however try to use it realistically, i.e. I don't hit full throttle in the hardest gear from a slow speed, or try to climb steep hills on throttle in a high gear.
      I use my legs as a guide to how I use the power and the gearing. It's an ebike, not an electric motorbike.

    Did you ever have any luck with the 2 chainrings? I've wondered why nobody has tried this, if nothing else to have a better chain line and larger ring for the faster gears while commuting and smaller ring for the slower gears for trail riding. I do both on my bike. I did my bbshd conversion this past November.

    • @mick2d2

      Hello Tim. I ran it for a while with both chainrings, changing manually (which was a bit of a pain).
      Last summer I decided to take the plunge and bought a Rohloff 14 speed internal gear which I matched with a BBSHD spider from Lunacycles and a Blackspire Cyclocross 44T crankplate to give me the perfect chainline.
      The Rohloff gives me the equivalent of several gears above what I previously had so I normally start in fourth gear and a couple of gears below, so I can go faster too.
      I must say I'm really happy with this setup, I think it's the perfect match for the BBSHD and a real pleasure to ride. There's a small adjustment to make compared to useing a derailleur, as with the Rohloff, you can't change gear under pressure, you have to ease off. You can however change up or down any number of gears, in an instant, even if you're not moving. This ability to suddenly change up or down five or more gears, gives you a lot of flexibilty. It also handles the torque from the BBSHD without any problems.
      Of course there's also no irritating derailleur noise or slippage!
      The only issue really is the price!

    • @mick2d2
      @mick2d2  4 ปีที่แล้ว +1

      Hello. The kit I bought (Bafang BBSHD) was advertised as "1000W".
      The wattage depends on the voltage and the Amps you can/are putting through the system, Volts x Amps = Watts.
      This is a 48V kit, but I'm running it with a 52V battery (14S9P - that's fouteen batteries connected to produce 52 V times 9, so 126 18650 cells altogether)
      When the battery is fully charged it's around 58.7V.
      It puts out (according to the Cycle Analyst) 32Amps, so 58.7 Volts x 32 Amps = 1878 Watts.
      The " speed" will depend on your gearing (the bigger your front crank and the smaller your smallest rear cog, plus the faster your pedal cadence) the faster you'll go.
      On the flat, this kit will easily power you along at 50+kph.

      @mick2d2  4 ปีที่แล้ว +1

      @@murselincelik8411 I think you'll find that the 750W Bafang mid-drive is the BBS02, not the BBSHD.
      The BBS02 was my first kit, with a 48V battery (13S5P) which is now on my brother-in-law's bike.
      Again, it wasn't really "750W" it was sold as a 500W kit, but under the motor it was stamped as "48V 20 Amps".
      The voltage range was 46.8V to 54.6V (fully charged), which equates to a wattage range of 936W to 1092W (at 20 Amps), so not 750W.
      Some people "overvolt" the BBS02 to 52V as well, obviously giving more power - 1008W to 1176W (at 20 Amps).
      I ran the BBS02 for three years and my brother-in law has been using it for the last three, so six years altogether and still going strong (with no repairs).
      I've been using the BBSHD for the last three years (again no faults so far).
      Comparing the two, the electronics on the BBSHD are engineered for a lot more power and it doesn't get as hot (even on the 52V battery).
      Sometimes the BBS02 would overheat and need to cool down if you ran it at full power for a long time in the summer or also on long climbs. This has never happened with the BBSHD even though I'm putting an extra 10 Amps through it.
      The BBSHD clearly has a lot more power and a lot more torque.
      With the gearing I have, it will climb almost vertical slopes!
      On a few occasions, the slope was so steep, I had to lean forward over the handlebars, to stop the bike going over backwards, and went up just on throttle, as I couldn't pedal in that position.
      The BBS02 couldn't do that
      They are both great kits though and both pretty fast with the right gearing.

    I have bought a 52v for my 750w bbs02. My 48v drops fast i think. I will use that as reserve. What was the biggest difference going to the hd?

    • @mick2d2
      @mick2d2  6 ปีที่แล้ว

      More power, in those occasions when you need it. Better cooling when using the extra power, the BBSHD has better cooling fins. Also, more peace of mind when it comes to the controller (unless you have the uprated BBS02 one) as the BBSHD is overbuilt in the electronics department with more and better mosfets or at least that's what I've read.
      To be honest, I was very happy with the BBS02. It ran perfectly for the three years I used it and it's still running perfectly for my brother-in-law who's used it for the last year. When I gave the BBS02 to him, this was a good excuse for me to "upgrade"! 8)
      The main upgrade really though was the battery, more than the motor.
      Most of the time I only use low levels of power, except when climbing really steep trails. This is when you do notice a difference as the BBSHD is pulling 32Amps at full throttle.
      The real upgrade though was switching from a 13S5P battery to a 14S9P one. This meant going from 48V nominal to 52V and from 65 cells to 126. I can really thrash my battery now if I want/need to. It also gives me well over 150km (I've never done more than 110km on the dirt trails I ride). Also most of the time I'm in the voltage sweet spot and rarely go below 50V. My old battery is good for about 90km and the last part only gives weak assitance as the voltage swing takes it down to the cut off if you push it. You're okay as long as you don't have a hill at the end!
      A few weeks ago we did another stage of a canal near where we live. I cycled into town (about 15km) and my brother-in-law drove down with his bike trailer to pick me up. We then went to the next part of the canal and did about 70 kms. He drove me back to town and then I cycled home (15km). After the 85km I'd already done, I just wanted to get home as I was knackered, so I wacked it up to level nine assist (about 1000W) and cycled home at about 40-45Km/h. I couldn't have done this with the old battery.

      Brian Bassett What do you mean by "the green button"?
      I'm really loving the Rohloff. I was finding the ten speed derailleurs to be a bit of a pain. If they get knocked about a bit, it then becomes nigh on impossible to adjust all the gears correctly. With the speed hub, there's no chain slap, it's like always being in the perfect gear. It's not quite perfectly lined up with the bling ring and it would be nice if I could get rid of the chain tensioner. Other than that, I'm very happy with it.

    • @brianbassett4379
      @brianbassett4379 6 ปีที่แล้ว +2

      mick2d2 - Do a search for "The Giant Green Button", it is a button to mount on the bars that hooks up to the brake cut-off. You can push and hold the button and the motor won't come one as you pedal. You will find yourself using it more and more and that saves power. I know what you mean with the Rohloff. Once you stop having to pedal to shift it makes things so much more simple. I was hoping not to have the tensioner too, it's so clean looking without one but after almost 8000 miles I have had no problems with any of it. My chain alignment is almost perfect. Have a great day.

      Hello Robert, I had no problems with the USB. I bought this cable:
      lunacycle.com/parts/bafang-parts/bbshd-parts/bafang-bbs02-and-bbshd-programming-cable/
      But I've also seen it here:
      fasterbikes.eu/en/matching-wires/198-bafang-bbs-programming-cable-usbmatching-wires.html
      YOU REALLY DO NEED TO READ UP ON THE SOFTWARE BEFORE MAKING ANY CHANGES:
      electricbike-blog.com/2015/06/26/a-hackers-guide-to-programming-the-bbs02/
      IF YOU DON'T DO THIS PROPERLY YOU CAN FRY THE CONTROLLER.
      Saying that, on the hacking guide it gives very clear instructions with several examples of how you can improve response.
      I use a slightly tweaked version of Kepler's (the pink one in the hacking guide).
      The tweaks I've done make the power delivery smoother and the power cut in and cut off quicker.
      I rode my BBS02 for nearly three years before changing this. I just wish I had done it before!
      When I started going out on my BBSHD with my brother-in-law on his BBS02, it was a real pain trying to match our speed, either I was surging ahead or he was!
      With this way of programming the controller it's easy.
      Power delivery is smooth and constant, none of that irritating surging that I had before.
      I have a pretty constant level of power delivery on each of the nine levels. (It's not 100% constant, because obviously the battery level changes as it moves from totally charged to discharged).
      What I have is (approximately with little variation)
      Level 1 gives 50W of assist (just about enough on the flat to compensate for the extra weight)
      Level 2 gives 100W
      Level 3 gives 150W
      I mostly use levels 2 & 3 for relaxed cycling on the flat on trails at about 20kph
      Level 4 gives 200W
      Level 5 gives 250W
      These two if I want to go faster, around 25-30 kph
      Level 6 gives 350W
      Level 7 gives 500W
      These will get you up most hills at a reasonable rate.
      Level 8 gives 750W
      Level 9 gives 1000W
      These will get you up virtually any dirt slope as long as you can keep the front wheel on the ground.
      Throttle I can use in any level from 0 to 9 and gives about 1600W
      This will get you up extreme dirt slopes when you have to lean your body forward over the cross bar to stop the bike from flipping over!
      This type of programming gives constant assist, with no surging. It makes the ebike feel like a normal bike, especially in the lower levels of assist.
      It also seems to give me better and much more predictable battery performance.
      Hope this helps!

Would love to see your new setup and how it runs. :)

    • @mick2d2
      @mick2d2  6 ปีที่แล้ว +1

      I'll post a video with my "final" setup. I don't think I'll be making any more changes for a while, as the Rohloff upgrade was a bit pricey. I suppose everything is relative to the use you make of things. I use my bike every week and the Rohloff is supposed to last for at least 100,000KMs!
      The final tweak was adding a LunaCycle 130BCD spider and Blackspire Cyclocross 130/44T crank plate as the chainline with the Bling ring was a bit crooked. With this setup it's perfect.
      I'm really happy with the Rohloff, it's like always being in the right gear, no derailleur noise or grinding, no chain slipping or popping, just puts the power down.
      With the battery fully charged (58.8V) it can handle level 9 of the Pedalec in the highest gear from stationary (I'm 100KG). Obviously I don't normally do this, as it's causes unnecessary strain on the components.
      As far as the gears go, the combination of the Rohloff 16T and the 44T, gives me more gear range than I previously had. I normally start in 4th or 5th gear and I also have a couple of faster gears than with the 11T cog.
      It takes a little bit of adjustment to the gear change, as you can't change gear under tension, so you have to ease up slightly in order to make the change. In practice, I don't find this to be a problem as the BBSHD has loads of torque, so it's easy to compensate for this.
      The great thing is, you can change through lots of gears at one go and you don't need to think about changing gear when you stop, or making quick adjustments at a road junction. The best thing is, it's just so smooth when compared to a derailluer, and pretty much bullet proof.
      In the last five years, I've knackered two Shimano Saint derailleurs, one got badly bent out of shape when the derailleur hanger broke and the other hitting a tree stump.
      In first gear, you can climb literally any slope. You can also adjust this further by changing the cog on the Rohloff. I think you can fit anywhere between a 13T-21T cog.
      You can see all the possible combinations using Sheldon Brown's calculator:
      www.sheldonbrown.com/gear-calc.html
      I think it's the perfect combination for the BBSHD.
