sensors how does he feel to drive it? a little mention about range and also whether you need all this power or not, if you haven't done yet, subscribe to the channel and now, let's move to the video if you guys followed my last live yeah, the one where I almost destroyed my brand new metric kit oops! now I don't know if I have to worry for the motor or for my floor you might remember that I left you without completing my build that's because I realized I had some problem with the chainring and particularly with my frame you might know that the first thing that you have to pay attention to is your bottom bracket both buffane and tungsten mid-drive kit works with bike with 60A to 73mm wide bottom brackets with an inside diameter between 33.6 and 34mm but unfortunately, that's not enough to be sure your kit will fit into your frame I'm not very good with drawings but this may give you an idea of the challenges you may face regarding your chainring my problem was here I would try to be as concise as possible the first thing you have to consider is that the probability that your chainring is going to be exactly at the same place as your previous chainring are very low so you might eventually be closer to the frame or far away from it in both cases you have to recalibrate your rear derailleur and if your new chainring has a different number of teeth compared to your previous chainring you might also end up changing your chain I actually had two chainrings compatible with my new mid-drive motor the stock one, counting 44 teeth and the one I ordered separately now my problem was that the 36th custom chainring was too far away from the original chainring position this would have caused my chain to be too much crooked their interaction so I wasn't able to use it the stock chainring counting 44 teeth thanks to his concavity was closer to the frame but actually so close that he handed up touching the frame things that you absolutely want to avoid so at the end I came out with a simple solution which is mounting the stock 44 teeth chainring adding the spacer that came with my custom chainring this way I gained enough millimeters to stabilize my chainring in the right spot not so far away, not too close to the frame now that you have successfully placed your motor and chainring the rest of the building is pretty straightforward about cable management this time I decided to have a different approach all the cables are routed backward from the motor passing by the center of the frame just behind the bottom bracket starting from there each cable takes its direction the main cable and the headlight cable are routed through the vertical bar of the frame from there the headlight cable is directed to the back of the bike this is because in my case the headlight cable will be used to power the rear light this particular light has been re-adapted to use the power from the cable instead of its battery the main cable instead proceed through the front of the frame then all its branches are fixed around the fork wrapper from there each branches is directed to the handlebar the battery cable is routed through the bottom bar of the frame as usual finally the speed sensor proceed backward through the frame to be as close as possible to the rear wheel if you remember my last video I show you that this build has hydraulic brakes but from the moment I installed the mid-drive motor it stayed under pressure for a bunch of seconds before get released it was quite strange and finally I realized why the mid-drive motor was pushing too hard against the brake tube preventing the liquid inside from flowing once I moved the tube aside it all started to work well again now let's address the brake sensor's topic while I was waiting for my hydraulic sensor to be delivered I made up a custom sensor that even if very fragile, worked perfectly fine I just opened the mechanical brake sensor that I had extracted the sensor part and simply zip-tired it to the handlebar keep in mind that this is just a simple bar on that if released sent to the motor the signal to disengage itself I was happy for a few days until I received the hydraulic sensors I tried all the possibilities to mount it correctly but with my brake levers there was just no way to install it in a way that was durable and comfortable so at the end I went for the simplest solution be aware that this solution works for me and it may not be the good one for your configuration in the last video I talked about the possibility to replace the hydraulic brakes with simpler mechanical brakes I decided to give you a try but only on the front one it took me a little more than 30 minutes to replace the front brake and at the end I was able to use the mechanical brake sensor that came with the kit some considerations now don't believe to do saying that mechanical brakes are inferior they are just different with pros and cons I just decided that for my specific configuration a mechanical front lever would have provide more control when braking and that's true while the rear one is more inclined to completely freeze my wheel thing that might be dangerous on the front wheel the mechanical brake offers the possibility to calibrate your braking and this makes me feel safer don't forget it's also easier to maintain it in the long run so yeah, two different braking systems on the same bike having one only brake sensor is not a big deal as long as your brake using both levers ok but how is it going? does it work the time and effort to build it? let me tell you guys, this mid drive kit is amazing before you ask me why I choose Buffang instead of a Tonkshankit you can simply refer to the table I showed you in another video I needed a bike for a mixed traffic area I don't need something to work out I need something that can bring me home without die trying to face the hill of the city my Tonkshankit is now the daily driver of my girlfriend and she loves it she used the bike to go to work and we love to hang out together with our bikes the BBS-02B is a caddent sensing motor meaning that sometimes if you don't select the proper combination of assistance level and gear it can assist you less than you might need or too much but once you know how to properly combine them with this 750W variant you can ride uphill up to 35 km per hour without any effort or run on a flat line at 55 km per hour I didn't try to go faster, that's too dangerous but I can get into you, it's pure fun I don't think you'll ever need something more powerful than this unless you need to power up a cargo bike and even in that case if you live in a flat area the 750W is more than enough where this build really shine is the available range my battery is a 48V 17.5A to put it in perspective I made a 15 km journey with 90m of total slope and at the end I went from 54.6V to 52, consuming just 20% of the total battery hey guys, I got some less stuff to share to give them more emphasis I'm running in my hometown now on my second 500W mid-drive build the last question I want to leave you with is do you really need all this power? let's not consider legal concern this time the 750W Buffenkid offers a max torque of 160Nm which may come really handy in case you live in a place with plenty of steep climbs now let me just step aside these scripts real quick and that guys is my build there's nothing fancy about it he has V-Breaks, ugly basket but actually is enough for what I need I got this pilot to secure my luggage now in case you live in a flat area with sporadic climbs going for such a powerful motor may affect your range if not paired with enough battery that's why I'm absolutely not planning to upgrade this build I got here which provides a 100Nm of max torque that's more than enough what I'm thinking instead is to increase its range with a second spare battery but this is the topic for another day just be sure you subscribe to the channel so you won't miss any future video on this and other builds I will make also don't forget to hit the like button thanks for watching, see you on the next one bye
