Burley Django Recumbent build

[rmwac]

Here is my first mid drive build... BBSHD with a 48v, 21AH battery pack. 42 tooth Luna crankset. Chain-line was perfect with everything right out of the box. Everything went together easily except for having to create an anti-torque bar to stop rotation of the drive unit. The bar works well, hung on the abandoned front derailleur mount with 2 "C"clamps. The stock toothed bracket did not stand a chance against the upward rotational forces of the drive unit. The Burley Django has a standard threaded 68mm BB, so installation of the drive was a breeze. The battery is only 6"×8"×4", and it fits with plenty of room to spare in my rear bag. I did add a cam lock strap that goes thru the bag's bottom, and around the rack, to further stabilize the battery. A 1" foam pad underneath shields the battery from excessive shock. I used one of Luna's motor-disengaging brake levers, and left the rear lever stock. I may use an add-on magnetic unit later. I also used the GearSensor, and shifting is smooth and seamless. I am currently using the stock Luna programming, but need to optimize for my riding, which is strictly rail trail. I'll need a number of battery cycles to get an idea of my range. Hope it'll be Hu-uge, ( to quote someone we all know..... :(

wish they made a set of handlebars for a curiser bike that were angled down like that. Looks comfy. All you need is a big screen

Rode my first "long" ride today, at Niagara Falls. 22 miles, various speeds, some overpasses to climb, etc. Started at 54.4v... rode it down to 51.4v. Running a 48v, 21 AH Luna pack. The visual percentage bar on my dpc-14 didn't drop at all. I read the voltage off of the battery's LED directly... which agreed with the numerical voltage readout of the dpc display. So, it looks like the outfit will have decent range. I'm not liking the PAS feel, having been spoiled by my wife's Trek Lift Plus, which uses a torque sensor. I'll have to further experiment with trying to make the BBSHD feel more like riding a bike again. However, the unit and my Burley are a great marriage. It would be nice if Bafang introduced a torque sensor for their drives.

I loaded the LIMITLESS profile, and found that the choices of assist are many, with subtle step-up's in power with each level, and right in my riding zone. This is a great profile for a rail trail recumbent build. Would work great on the road, too. Bike now feels like it has a torque-assist sensor. Running 150-175 watts, doing 15-16 mph with no strain, and no 'air guitar' pedaling, cadence of 80. Between the gearing and the PAS, I'm at last able get the right cadence with the right amount of pedaling pressure, WITHOUT hitting the speed cutoff. So, the motor is always pulling. Throughout my ride, the motor was barely warm to the touch. I also highly recommend using the gear sensor. My shifting under power can't even be felt. The 48v 21 AH Luna battery is only 4x6x8, fits in my rear bag with room to spare, and I still don't know what it's really capable of in range. I have 37 miles on this charge, and still have 49.0 volts. (One "Bar" on the dpc-14 battery icon.) My goal is to be able to ride our local 62 mile rail trail on a single charge. I think the battery may well d o this... and more.
