Electric assist conversion begins

The BBSHD kit arrived Saturday from LunaCycle. I delivered the motor/battery kit along with our Rover Tandem to Velocity Pro Cycle today. I'll drop in on Adam and Brad tomorrow to learn which wiring harnesses are short ... it's a long way from the battery rack at rear tire to the new motor hanging out in space in front of the single chain wheel. So, no rides for a few days. We'll see how this goes :-)

    Instead of putting the battery at the back, look at putting it behind the pilot seat. Wont have the current loss that way. Just a suggestion. Look at mine here: www.bentonabudget.blogspot.com
  • I put a BBSHD on my 2014 Rover last winter and am loving it! I'm confident that you will love yours too. I did it with the idea of converting the Rover to a tandem once I purchase a new folding and suspension trike to replace it. I tend to have a lot of brand loyalty and hope I can wait for TerraTrike to offer such a trike. But I digress.

    I am extremely interested in your project. I would like to know what sort of hub/gearing you have. My Rover is equipped with a Shimano Nexus 8 speed. I am contemplating purchasing a NuVinci N380 along with Efneo's GTRO 3-speed front gearbox. I think this would be an ideal setup for a TT Rover tandem.

    I fabricated a hardened aluminum mounting plate to allow one or two batteries and mounted this on the frame under the pilot seat. The batteries mount on the underside of this plate. This keeps the batteries This works OK for me, but my current setup requires me to remove the batteries for charging. Even though I can quickly do the R&R, I wish I had waited for TT to release their under-seat rack which would allow for charging while trike mounted. Unfortunately, TT never announced the rack until it was actually released. I believe you would do well by following the suggestion made by squirrelpie0. And you should check out TT's Low Rider Rack on page 3 of the accessories page. While a bit pricey ($90), I have test ridden a TT so equipped, and immediately suffered rack envy.

    Best of luck with your Bafang installation. If I can be of any assistance, I am glad to help.
  • Thanks both. Tech at Velocity Pro Cycle is also a retired engineer so we communicate! He suggested mounting the battery on the frame in front of front seat. I did buy the Low Rider rack and planned on mounting battery there.
    I'm going to be interested in weight distribution.
    I rarely ride single on the Rover Tandem but rear wheel traction in lower gear ranges is an issue in gravel. I intend to take loaded and unloaded weight per wheel readings when it's complete ... or is it ever complete?
    I sure understand the current loss with battery at rear and appreciate that point.
  • Under seat rack? I've missed that!
  • On my Rover placing the battery behind the front seat distributed the weight of the BBSO2 installation nearly equally. Granted different on a tandem. Behind seat, out of way.

    Anybody have a notion about placement of the LCD Display for BBSHD? Bike shop wants to mount on the boom ahead of the pilot seat because the mount doesn't fit the handlebars. I was thinking there were some adapter rings in the bucketful of extra doodads Luna shipped. The question is, "Do I just refer to the display for info or am I inputting and fiddling with it whilst riding?"

    Thanks for input on battery location. I'm going to stop in at the bike shop this morning and bless the component locations before they're tightened up ... some may be moved around later. I don't have enough experience on board (and certainly not with e-assist to take a strong position). We're adding about 33 pounds of gear so it could matter, I guess. On the other hand, we go "low and slow" most of the time.

    I'm determined not to stress the details too much and I'm a bit caught off guard this has moved so quickly. The wait for additional cable will slow it down.
  • sounds like the lbs is new to this stuff. check out http://t-cycle.com/-c-71/
  • Mine located on left steering arm. Only have a short cord from lcd to control pad. Used an adapter I got someplace. Memory? Take a look at picts on my blog. Www.bentonabudget.blogspot.com

    Thanks! You are correct JamesR. There are about 2 trikes in town ...
    Will get both these to tech by morning.

    Update: Ordered cable extensions today from Luna, got confirmation tonight that all were shipped. They do NOT offer expedited delivery. Imagine ordering from Amazon and being told it has to come by Post Office or UPS ground! Only complaint with Luna so far.
  • Amazon IS using the post office these days, but still meeting their Prime 2-day delivery schedule.
  • JamesR, found double end cockpit clamp at TerraCycle and ordered today. They called TWICE ... and shipped today! Jrobiso2, the second call was to suggest USPS 1st Class instead of UPS ground. Thought it would save several days. I've had some terrific service from them, Luna, and TerraTrike as we determine our needs by discovery not planning :-)
    On a side note, the tech and his strong legged assistant took the Rover Tandem for a spin and got it up to estimated 30 mph. My high on a long descent is about 18 :-) All their cusstomers are taken by it ... not many recumbent tandems around here.
  • All the cable extensions arrived from Luna today. Hopefully putting the trike on the road Friday. 79 degrees expected this weekend. On the other hand, we have LSU football in town Saturday ... the roads may not be safe.
  • Shop guys took tandem out for a trial run today. All impressed with performance but there's a glitch they think is a faulty wiring harness. Getting the specifics then taking up with Luna. Otherwise, tightening, adding rack, figuring how to get left mirror back. Should be ready to go Friday. 79 degrees Saturday.
    So strange NOT to be doing this myself.

    Battery connector intermittent? Clips in battery adjust, beND to grip prongs on cord to motor? Cover w vaseline. Drove me crazy until diagnosed. Also used straps w velcro to GUARANTEE battery cannot wiggle in quick release base
    Heavy enough wire from batt to motor?

  • Good suggestions, thank you. I was there briefly and don't have details of the complication yet as we mostly were concentrating on the positives. Interesting that every employee was smiling. The owner came, smiled and said, It will fly! He showed me test ride video from stoker seat and they were passing cars downtown. That's fine ... I just want to pull steep hills ... We've got'em.
  • Not my best photography but it's here. Took a quick 2 block ride to see if I could get up the drive ... Pretty amazing.
    Still corresponding with Luna about the bug in the throttle but hope to have replacements in a week.
  • Notes from first ride:
    I got an Error 21, speed sensor fault. The sensor may have been bumped in transport to home in spite of my efforts. We'll need to recheck adjustments there.

    The battery went from 50% (probably should have charged last night) to an apparent zero on the display in less than 6 miles BUT it still pulled up my driveway. Installed charger, set charger for 80%, immediately got 38% reading on the motor display ?? Charger didn't stop at 80% so I disconnected when it displayed 100%. Display dropped to 93% without the charger. May have issue with charger and/or display.

    With motor at bottom setting of 1 and in first gear, the trike sailed along comfortably. I could not shift up past 6th so I wonder if 1st gear on the indicator was actually 3rd. We'll need to adjust shift cable. Techs got it up to 29 mph on test ride ... i have no interest in that :-) The five hills on this morning's ride were non-events. Just cruised right on up.

    The larger chain ring and/or the possibility of the shift indicator being off made starting without the motor on difficult. I'm planning on using 0 setting at least some of the time.

    The new harness should ship next week. They are shipping USPS 1st class so should be in quickly. It could have to do with battery and speed I guess. After we reset that and another ride or two, I'll take up speed fault, battery and charger with Luna if needed.

    I'll want to mount the accessory rack and install the clipless pedals on next visit. Those cable heel retainers are awful and going back.

    Low Rider rack from TT looks good and is definitely low. Will probably move battery back there on 2nd set of tweaks. Will need to find or make cable extension from motor to battery.

    Velocity Pro Cycle gave me a terrific deal on the installation. The owner said he reduced his labor rate and both the techs worked on it off the clock some. I could tell they were really into this project. Everybody in town knows my wife's story so that may have played a part. At any rate, I'm grateful.
  • When you're all done can you post a complete list of hardware and the costs? I'd like to do something like this to my 2016 Rover.
  • Sure will [b]Jrobiso2 [/b]. Working it up now.

    Colder weather reduces battery capacity, and more so as the colder temperatures persist. Once the battery gets warmer (indoors) the battery capacity comes back to normal. Depending, of course, on what metal/chemical type of batteries you have.

    You could create an insulated cover to perhaps keep the battery warmer. Nice ride BTW.
