    This mornings ride was a 50 miler. Using known locations, I went from Knott's Berry Farm area to Seal Beach, across the beach all the way to Newport Beach Pier on the peninsula, backtracked to the Santa Ana River Trail to the Pond on Katella Ave., and basically took Katella Ave. back to my starting point (Orange County, So Cal). From the Huntington Beach Pier to the Newport Beach Pier there was a nice mild tailwind, so I put the assist level at zero and easily pedaled 12-13mph with little effort. Rode about +/-20mph the rest of the ride. Started with 54.4V in the tank and ended with 45.7V. That's an average of 0.174V per mile. Still has 3.7V in the tank. The GA battery pack is performing flawlessly. Have I said I love this ride? Lol... ;-)

      Hi Rider. I’ve been meaning to comment sooner. Really enjoyed following your journey on this project because I’m planning something similar. Great build and comprehensive reporting. Confirmation for me to start something similar.please feel free to keep updating.

    Added a pair of titanium pedal extenders and that has solved my sandal heel hitting the crank arm on the forward down stroke issue. The huge pedals really stand out now. I've had several inquiries about the pedals while out riding. With the extenders my feet are now centered on the pedal and not hanging off the outer edges.

    My 6V headlight arrived, but the lens was cracked so I'm having to deal with that. A 6V tail light from over seas should arrive soon. These will get wired into the controller 6V lighting wire and will automatically come on any time the power is on to be used as day/night time lighting.

    Some thoughts on my 4 bike stable:
    I'm seriously considering selling my Soma B-Side now that I have this ride dialed in. Too many bikes sitting around not being used. The Niner Jet 9 just got returned to pedal only with a Sunrace 11-50 cassette, so I can ride it with my friends in places eMTB's are not allowed. Added Answer 20x20 Pro Taper carbon bars, Thomson stem and Lizardskin Northshore grips as well. That will be my pedal machine going forward. May sell off the complete MY1018 450W/36V motor and battery in kit form or put it on my old Schwinn Crosspoint and sell it off as an awesome commuter eBike for someone. The Soma B-Side is going back to pedal too, but will retain the Gates CDX belt drive and 3spd IGH. Someone will really like this 3spd IGH single speed slayer; having a 33% lower and highr gear on both sides of the standard single speed gearing is sweet. Ex-BMX riders would love that setup.

    In the end, I will have the eSurly ECR with 21Ah & 17.5Ah batteries, and an extra complete BBS02B kit; plus the Niner Jet 9 pedal trail rig. Once I'm down to 2 bikes again, I can think about another build for my extra BBS02 and/or just keep it as a backup. Both batteries can be mounted on the Surly ECR for some real epic long adventures or weekend 2-day/1-night bikepacking trips.

    Too much fun! ;-)

      We have light!

      Haven't tried riding it at night to see how bright it is, but the 6V controller light wire works and comes on when you hold the "+" power level button for a few seconds. I'd like to add an inline strobe, so both lights blink. If anyone knows where to get one please post up. These are simple 6V lights like the hub generators use.

      Looking forward to my first night ride. I can now install my chargeable headlight on my helmet. Friends say it is best to have two headlights when off-road riding at night; one on the bike and one on your helmet to light up where you are looking.

      Saddle swapping a-g-a-i-n...

      Got a wonderful deal on two new saddles to try; a Brooks C17 Cambium Carved and a Selle Italia SLR Max Gel (L3). Took the Brooks out on a 20 & 35 mile ride and couldn't get comfortable on it at all. Brooks Cambium saddles don't need a break in period. They are useable right out of the box; unlike their leather brethren. It was obvious right away that Brooks "taint hammock" saddles are not for me. I suspected so, but had to try one because so many people like them. I am finding out I like flatter saddles with large cutouts. They say you either love the Brooks or hate them. I'm in the later camp. Already sold it off to another guy for him to see what all the hype is about.

      Installed the Selle Italia SLR Max Gel and loved it from the start. Three simple seat rail and angle adjustments later I was in pedaling heaven. Having a normal seat nose back was great, as I use it on my inner thighs when standing and turning (couldn't do that with my stubby nose ISM Urbaine - which I still really like). The narrow nose also allows you to bring your knees in when stretched out and tucked. I think this one is a keeper. Not sure if I will leave it on the eSurly ECR or put it on my Niner Jet 9 MTB; now a pedal only FS trail rig. Going to log several hundred miles on the eSurly ECR before deciding.

        Gave the Selle Italia Max Gel Flow a few hundred mile workout on this ride and still love it, but moved it to my (now pedal only) Niner Jet 9 FS Alloy XC rig and put the ISM Urbaine back on the Surly ECR for some epic adventures to come. It's a little better for me on long slow rides that I sit up straight often on.

        Added a pair of Blackburn cargo racks to my front fork. Slowly getting equipped for my first eBikepacking overnighter. I found a way to configure both of my battery packs into the frame bag. That will give me a whopping 38.5Ah/1,848Wh of range to climb the Eastern Sierra's up to the Brook and Golden Trout lakes. Might not get out there this year before the snow falls, but trying to prepare. May even try a Big Bear overnighter ride first or something even closer with a campground Saturday night and local trails both days to see how it rides loaded up.

        This eSurly ECR is now my only electric assist bike. It really is close to a do-it-all rig, sans any need for suspension. The large shoes aired down with Thudbuster S-T works well at the slower speeds I ride at these days. Still have the Soma B-Side in Gates Belt Drive pedal form and the Niner Jet 9 FS XC mountain bike setup with a Sunrace 11-50T X 30T for pedaling with friends on local non-motorized trails. The electric bikes have really got me in much better shape over the last few years. Hoping to keep that tread going with riding both pedal and E-assist going forward. The Soma and Niner pedal rigs are a pleasure to ride when I want light weight and a good workout. It's great to be back in the saddle again.

            I just recently passed the 1,000 mile mark on this build. Hoping put the larger 21Ah rectangular battery and bracket inside the bag this weekend. I’ve been using the smaller 17Ah battery and not having range issues for 50 mile rides, but it does give me some mild range anxiety because I approach the battery shutoff level of 42V at times. Riding for me is all about the enjoyment of being outdoors while getting a needed cardio workout doing something fun. Anxiety is not part of that equation.

            Because of the weight of eMTB’s I’ve had to rethink how I transport the bike. My Mini Cooper DD has two Rockymounts Euro Pitchfork racks on it that aren’t rated for the weight of two eMTB’s and lifting them up there isn’t an easy task. I ended up installing a 1.25” trailer hitch for a 1UP-USA bike rack. The nice thing is the trailer hitch is completely hidden behind the bumper and skirt on the Mini Cooper so it doesn’t look unsightly, plus the 1UP-USA rack doesn’t require the removal of the front wheel. They are made in the USA and are very high quality all aluminum construction (no plastic), but not cheap. It is rated for 150lbs. total (one bike rack weighs 23lbs.), so a two bike rack will carry two 50lb. eMTB’s. I’ll only be carrying the eSurly on the 1UP, but can also carry both of my other two pedal MTB’s on the roof racks. This hitch rack will move from car to car if I change vehicles over the years too. When it arrives, I’ll post up photos of the bike on the rack behind the Mini Cooper.

              What an awesome trailer hitch bike rack! Installs super easily and folds up at a 90* or 45* angle and locks in place when not in use. It also folds down past flat for access to a tailgate. To mount the bike you simply fold out the tire supports, lift the bike into place and push the tire supports upward onto the tires. The ratchet latchs automatically lock the tire supports in place holding the tires and bike secure (accepts up to 3.1" tires on the stock rack). To release, simply push down on the tire supports and lift the ratchet latch on each tire, then lift the bike off.

              This puts me one step closer to getting out for an overnight adventure eSurly ride and puts many more local trails within driving distance up play.

              Very happy with this all-be-it expensive purchase ($300 for silver - $350 for black).

                Took a quick 40 miler this morning from Anaheim to Long Beach and back. What a beautiful day for a ride!

                The motor has started to make a click or clank noise with each turn of the crank. Not sure what it is and it doesn't affect the motors function in any way. I started a trouble shooting thread here:

                https://electricbike.com/forum/forum...pedaling-bbs02

                Wanted to get a nice ride in before removing the bottom bracket to check the bearings and possibly the freewheel clutch pawls. Kind of sounds like a pawl clanking around on each turn of the crank. Hoping it is something simple. This motor only has about 1800-2000 miles on it so far.

                  Glad to report the clicking noise turned out to be a copper washer I put between the crank and pedal to protect the crank surface from damage. The copper had compressed just enough to produce an odd creaking clank noise. Who would have guessed that?

                    Rider,

                    What width of bottom bracket did you end up going with on your Bafang? 68/73mm option? Or the wider 100mm option?

                    I ask because I just put a 100mm BBSHD on an ECR, and the chainline is very out of whack. Thinking I should have went with the smaller size, but I was worried about the fit of the narrower version.

                      Went with the 68-73mm BBS02B 750W/48V version that I have had such good luck with for several builds. IIRC I used a 3mm spacer to clear the chainstay with a 42T Lekkie Bling Ring.

                      Haven't worked with any BBSHD motors at all. More power than I need and they weigh a lot more.

                      A 100mm BBS02B would have the same chain line as a 68/73mm BBS02B and a better centered Q-factor; the spacing on the chainstay side is the same on both.

                    #41
                    Added a Blackburn Outpost World Touring rear rack and mounted a tail light to it, plus a custom kids license plate for the jealous roadies as I speed by.

                    Got to keep the mood light and humorous on the trails... ;-)

                      Now that I’ve embraced my inner “cheater” with a little humor to hopefully get a smile from defeated passees. It will be interesting to see what if any responses I get. Hope they can pick up on the pun through their anger. Might turn out to be a conversation starter when parked.

                        Well, I've sheepishly uttered, "on your left - I'm cheating" going up a hill, to a pair on a tandem and a guy on a trike.

                        I figure someday they'll motor up, and things will be back to normal.
