    BBS02 on 2009 Muddy Fox Xernt 700c Hybrid Road Bike!

    Well, this old girl has been neglected in my garage for too long! Almost 7 years ago I was experimenting with the original Kepler friction drive, and when I tried to make this road bike work like a touring bike (built a custom cargo pod of coroplast and such to haul too much for what it was designed) I side-lined it for my first home-built mid-drive build.

    I also built my first set of 700c wheels at UBI in Portland in their wheel building class, and finally decided I needed to get it back on the road to take on trips to the Columbia River Gorge Bike Trail (built on the bed of the old highway) with my dad, he's be jonesing to do this ever since they built some of the new sections a few years back, and my cruiser doesn't exactly fit on a bike rack ; )

    The official home page for WSDOT. Take a look at how we keep people, businesses and the economy moving by operating and improving the state's transportation systems.




    It just so happens, that this bike is a PERFECT candidate for the BBS02! :D



    This is shaping up to be my cleanest build yet! The motor just slid right in there, no fuss no muss! Only took 2 thin washers from old caliper brake pads for the mounting bolts, and once a get a couple items still in the mail, it will be on the road! It should hit at least 30 MPH with moderate pedaling, I'm guessing closer 35 with me on a good day pedaling my guts out. : )

    Gonna use some fabric wiring coverings for autos to make a nice clean factory look. Got the battery connector tucked up inside the battery mount, just need the rest of the kit! Huge thanks to Eric & Ashley working so hard on getting these kits out even while moving to the new location and making wedding plans! Can't wait to fly by the roadies with my big Ebike Grin! >:D

    Nice and clean!

    Bring a large Allen wrench for the crank arms on your 1st couple rides of any distance. My experience they may loosen a bit if/when you significantly pedal. Don’t allow them to work loose and they will usually seat-in and remain secure when re-tightened early.

      Thanks! Good point on the Allen, I usually have a few tools, but a 8mm Allen isn't usually one of them! I will make sure to bring one on the maiden voyage. : )

        Got the rest of the parts in the mail yesterday! Had to pick up a rebuilt bike shock from Traction Works in Portland, and I just couldn't pass up the long ride in such amazing weather! Anyway, first thing this morning I finished putting everything together:





        Tried something new with the cloth tape I got for wiring looms of cars, I think it looks nicer than using zip ties:















        Got some pretty good speed on the flat, around 34 MPH, friend took it down a nearby hill and hit 38! (that's cheating! ;-P )

          You know, I now have a 36T Lekkie ring, and I really love it! We have some pretty steep hills in Oregon City, and after blasting up a very close-by one near the house, I couldn't resist heading for a short 10 mile ride down the hill (this was at about 6:45 pm lol!!) along the river trail, and turning back at Gladstone! I really am amazed blasting UP steep hills at 29 MPH!!!! :o

          I lost some top end from the 42T Lekkie, sure, but I don't really need to be geared for 40 MPH, now I can use all my tall gears, and have the granny (11 - 34T Shimano Mega Range) for if I had "too much fun" and run the battery down, but NOT LIKELY! :D I have gone 40 miles using just about 10% of the battery on the Springwater Trail in Portland, and I never use above assist lvl 3 except on hills! If I use over assist lvl 3 on the flat, I am just "clown pedaling" with the motor doing all the work! ;)

            Wow, so apparently if I post too many links to pics, I break the post? LOL!!! Anyway, I will post highlights then I guess, but Cliff Notes: LOVE LOVE LOVE the BBS02!! I have now installed a Lekkie 36T and am climbing 5 - 7% grades at 29 MPH!!!!! :O Went on a quick 10 mile ride last night to test it out, after seeing how it blitzed a nearby steep road, to Gladstone & back on the river trail, and WOW!! Here are some pics from recent rides in around Oregon City & Portland!

              Nice thread... The first thing I thought of when I saw your first picture is that I don't missing sliding around under my buggy on a creeper getting covered in rust and dirt. Another big and vantage of ebikes:)

                Awesome bike, pics and riding! Sorry, photos are still a work in progress here but thanks for sharing what you did.

                Have you needed to retighten much on the BBS02 installation? The big nut, crank arm bolts, that sort of thing? I tend to bring along 8mm allen wrench 1st few long trips on a fresh BB install to check and retighten crank arm bolts.

                  No worries on the pics! Looks like the first posting worked after all, maybe it just didn't refresh at first so I thought it didn't go through. : ) I have only had to tighten the crank bolts once, and that seems to have done it, I did have the "bumper" I installed come loose (I wanted to prevent the possibility of the motor loosening up and moving, but the "bumper" material came loose, time will tell, I might end up making a modification to the mounting plate to give it a bit more to hold onto in some form of "torque arm" much like I have seen California Ebike's solution ... something adjustable along the lines of the old Amped Bikes torque arm maybe ...
