It is a stop gap because the best case scenario I can see is to just get a bigger battery made for the downtube, like a 20-25ah one and make a new cover plate that has depth enough for the extra cells and fits as stock in the end. Probably just do away with the case and go sideways with the...
The heart of an E22 frame is the Bafang G510/M620 motor. It is a big motor and likes to burn wh's if you are out by yourself riding at a sporting pace but when riding with a more EU/Class 1 compliant bike it uses alot less I have found. In order to do longer than 20 mile rides at a sporting pace...
Never ceases to amaze me that for such a heavily populated island that doesn't look that big on the globe the UK has such a large amount of wild and open land.
I'll be interested to see how you get on with the 52v vs. the 48v Neeko? Transformed the bike for me and now I am very happy with mine whereas before I was wondering if I'd made the right decision? Is your 52v 18650 or 21700?
Keep in mind that wh's are calculated as (system) volts x ah = wh's. However in reality due to the low voltage cutoff programmed into the battery management system module to keep the batteries from going below a certain voltage per cell that would degrade them a battery might provide up to...
If you just use a front hub motor and pedal your bike will be 2 wheel drive without the extra weight and complexity of the additional motor. If you don't want PAS get a controller that allows for cruise control so you can set and forget the throttle when possible.
I believe that Green Bike Kit...
Put this bike together yesterday with my son for him to use from parts in the shed.
He didn't want a front fork, said he was still young.....didn't argue with him. He is a fly fisherman using the Tenkara method so simple is best for him and this will help him get to the streams and lakes with...
Easy to check the BMS by removing the 4 screws holding on the dis charge end oover plate. I would be surprised it is not just the same 30A as my stock one. The problem going up in BMS Amps is also the BMS gets bigger and real estate in that case is what it is.
Other than what companies like Trail Watts has come up with for range extenders I don't think there are any options available due to Spec's proprietary electronics. Which must be really expensive to implement because I just bought a 780wh 52v 21700 cell battery for my off brand bike for half...
Day turned out nice here so got to test both batteries. The, 48v which started at 48v, did great down to 43v then started to taper off until down to LVC @ 41v. Took 672wh's to charge back to 54.5v. Not too bad from a 720wh rated battery and frankly about all I was getting out of the stock 840wh...
Neeko, I don't have a very accurate way to measure the weight of the batteries but by feel they all weigh about the same or close to it. The only way to get a lighter battery would be with less Ah via less cells or a non cased battery altogether which I don't want. As it is in order to get as...
Just received two 21700 cell batteries based on the stock case that fits the E22 frames, as well as the other E series DengFu frames I believe? One is a 15ah 48v 720wh and the other is a 52v 15ah 780wh both with 40A BMS. The stock 17.5ah 48v 840wh one that came with my Z1 is not the best...
I have an old Ultimate repair stand that 90% of the time I just have set up with the jaws wide open and put the nose of the saddle in there and let it hang. Gets the rear wheel off the ground enough for removal and lubing purposes which are what I do mostly it seems.
The hardest part with...
I find it is hard to be timid with an E22 frankly. Now that I have my program dialed in and better used to how it handles and what it will handle as long as a firm commitment is made it is a hard beast to hold back!
As far as calibrating the torque sensor goes, after my initial response and...
