Looking forward to hearing if you find an alternate rack with a lower shelf that is wide enough. I'm just starting a build for my wife and chose the 52v slimline as well. My plan was to do something very similar to what you did and I've already ordered a piece of 1/4" aluminum plate to mount it.

It just came today. I have most of the fitting done and made a few improvements over the old installation. I will have some photos up in a couple of days. I learned about the rack from this thread.

Where did you get one of those sturmey archer hubs with the cassette? I been thinking I might like to try that, such a neat idea.
Is that a CS-RK3 it's called? Is there a place that sells it with more than just the hub or do you have to buy the shifter and separate?Comment

The Sturmey-Archer site: http://www.sturmey-archer.com/en/products/3-speed shows 4 of these freehubs. They come in silver and black different spoke counts and with or without disc brakes. The freehubs are Compatible with standard MTB/ATB 9 and 8-speed cassettes• Compatible with standard MTB-ATB left hand shifter for front triple chain wheel. http://www.sturmey-archer.com/en/pro...l/cs-rk3-black
I was able to use my Shimano cassette and trigger shifters from another road bike. The only problem is the shift numbers are backwards. One being the highest speed and three the lowest. I really like it. You have so many gear choices that I didn't have to figure out what size drive sprocket I needed. I have 8 drive sprockets for any situation on the cassette.
I normally pedal around in 6th on the cassette but the other day when riding with younger non-ebikers I dropped to 5th and PAS 1 of 5 to extend my range and not over run them. I bring up the rear.
I got my hub from ebay: http://stores.ebay.com/The-Bikesmiths-Store . They don't have one now they only had the one when I bought it. I suspect someone ordered it and then didn't buy it. It came with a small parts kit which I didn't expect as they can vary slightly depending on your dropouts. I paid $93 shipping included. I did very well on that purchase.........calfeeLast edited by calfee20; 09-10-2016, 09:17 PM.Comment

I got a new rack to mount my 52 volt slimline. I bought it from Evelo electric bikes. They do not have the rack listed on their web site so I called and completed the transaction over the phone. Their phone # is Toll free: 877-991-7272.
The rack looks OK to good. The welds could be better and on both sides of the tubes and the finish could be better. It is not a Topeak.
Here is a picture next to old rack:
I upgraded the two mounting bolts on the rear dropout from 5.0 by .80 mm to 6.0 by 1.00 mm. I could see the smaller bolts breaking but not the 6 mm ones.
In the foreground is the 1/8th Aluminum plate I used to secure the battery mount to. It was used in the old installation and I managed to reuse it by drilling a few more holes.
The brackets that go to the seat tube could not be used if I wanted to get the rack as low as possible so I used the brackets from the old Topeak. You can see where I cut the rod on the left side to clear the locking mechanism of the battery mount.
The battery mount needed to be spaced up a bit clear the round bottom rails. My aluminum plate is 1/8" and I used 1/8" of rubber to make up the rest. The battery just slides in. You have enough room and no more.
Here is the mounting plate screwed in ready to receive the battery mount.
Finally with the battery in place.
Now I can see myself carrying a second battery for some serious range. For my part I feel this was a worth while upgrade...........calfeeAttached FilesLast edited by calfee20; 09-10-2016, 09:14 PM.Comment

Why exactly do you want to get the fatter version of this bike?
This is a great build thread, nice work.Comment

Man, I've been considering converting my Electra Super Deluxe to electric, but have been daunted by the lack of resources on the project. Then after some significant scrounging of the interwebs... Lo and behold, there's a cat who did the same project I'm considering! Ehmergerd! Hats off to you brother! I may soon be standing on the shoulders of giants! So far I'm in the process of upgrading the brakes; installing a front drum brake and then... who knows? I'm sure I'll hit you up with some questions soon. Thanks again for posting!Last edited by Voltron1138; 10-14-2016, 05:52 PM.

Disc brakes are easy. The front fork is steel. I could weld tabs on with my Miller MIG. The rear is even easier. Just drill 2 holes and cut a clearance notch.Originally posted by g725s View Post
The ISO tabs can be purchased from http://www.paragonmachineworks.com/ . They have all kinds of neat stuff for frame builders or anyone who wants to do some modifications.
This front fork tab costs 8 bucks but then maybe it would be easier to buy a whole new fork. Paragon also gave me an idea for increasing the wheelbase because a couple of more inches and you could tuck a battery behind the seat post Picture a couple of inches added between seat post and rear wheel.
The Elecrta with those large flat triangular rear dropouts can lead to all sorts of possibilities.
Then add some pieces from Paragon and you have horizontal dropouts for an IGH and room for a battery behind the seat post.
Oh and look the disc brake mount is built right in. This piece is for the left side.
Why do I want fatter tires? I keep telling myself it is for suspension on a rigid frame bike plus the Electra Lux Fat is a very large frame. I am 6' 4" and 275# and I have a 35" inseam for bike frame measuring purposes. I hated putting 125 pounds of air in skinny road bike tires because of my weight. The increased air volume and lower pressure just makes everything nicer and the BBHSD makes up for the sluggishness of a cruiser. Spinningmagnets said he could bash into and jump a curb with his Electra Fat. The real reason that I don't want to admit.........I like the way it looks.

I have rearranged my controls a bit. The color display was shifted to the left because the main harness wire was long enough. This allowed me to move the switch control right up to the left grip and the thumb throttle is also closer. Having these two controls close to my left thumb is a vast improvement.

I bought a BBSHD kit originally intended for the Fuji Nevada that I put together. the Fuji had max diameter handlebar. But even then the color display mount did not fit it totally snug. Now trying to put the color display on the Electra Lux, the color display mount is WAY too big and I can't find any adapter/bushings for it (I must have tossed it out ). I'm wondering if there are different size mounts. -
I found the bushings. I did not need them before on the Fuji build so I tossed them in the little bag they were in to the corner of my workbench and forgot about them.
Right now I'm going to use the Electra Grips, I would probably like to get some grips like the ones you have there, but with the 7 speed shiftier I need a type where the left one is longer and the right one is shorter for the 7speed shifter, and also want them to be all black in color if possible. But the Electra Grips will do for now.Last edited by g725s; 11-25-2016, 05:33 PM.

Well it has been a while and I have been working on another bike. The plan was to transfer the Luna kit from this bike to the new bike. Some initial tests have changed that plan. The new bike is going to need a front brake improvement that may cost up to $200. I am putting that build on hold until I can get a complete new kit from Luna. I will not take this bike apart because it simply works so well. In the meantime I am going to improve this bike. I have a pair of Schwalbe Big Apple tires on the way from BikeTiresDirect. I couldn't resist the price, $28 each and free shipping.
Then a new chain and close ratio cassette and some handle bars with more pull back. Last will be a body float seat post shock absorber, but the whole seat/seat post will be swapped between bikes...........calfeeComment

This is a great thread! Looking for a bit of feedback, I'm a newbie looking to do a first e-bike build for the bride who has a flat tire (a bum right foot). Been searching the build threads trying to find a setup that will work for her, both in FORM and function (it's for the bride, so style matters). Anyway, have gone thru several motor/frame alternatives and now narrowed my search down to finding an Electra Cruiser 7sp, with a step thru frame for a doner bike and throwing on a BBS02. I like how you were able to shoehorn the BBSHD into the frame! NICE JOB! VERY CLEAN!
First...I'm looking at the BBS02 ILO the BBSHD, (This is a recreation ride, so not too worried about power & distance). My gut says the slightly smaller motor/frame of the BBS02 may fit just slide inside the peddle forward step thru frame without modification...I do like your tool to make the dimples to adjust the frame though, nice job! Has anyone tried a BBS02 on an Electra Cruiser Step Through frame?
2nd, the stacked back battery rack you found is a really NICE alternative. Very clean! I couldn't find that battery/rack setup anywhere, except on commercial/retail builds. What model battery did you use and where was it sourced, I don't see that style flat rack battery on the Luna site? I see a contact number above for the rack, sounds like you needed to talk them into selling one though THANKS!
3rd, the Electra Cruiser Step Thru 7spd come stock with a SRAM Revo shift & 7sp derailleur, I presume also a SRAM chain. I was looking at the Lekkie 42T Bling Ring for the front drive. Have seen at least one note that this chain ring does not play well with SRAM chains, anybody have any experience with this issue? If that is the case, will SRAM play well with the standard chain ring on the BBS02?
4th, I see your build had to extend the BB with an adapter, was this for clearance or did you just buy an over length BBSHD for flexibility? Is this something that can be specified? I have also seen at least one other Electra Cruiser build that actually cut down the right side of the BB to achieve a better alignment...really seems excessive and a one way trip. Does the BBSHD on the Electra shift the chain ring too far out and mis-align with the cassette? This seems like a LOT of work/risk and I would think a better solution w/b something like a dished chain ring (like the Lekkie noted above). Any thoughts on how to avoid a miss-match mis-alignment would be appreciated.
5th, Rim Brakes....OK? They are standard on the doner I am considering, and would like to keep them if possible. If not, another challenge. Any thoughts on if they will be sufficient, though I'd think they'd work ok.
I'd LIKE to use the KISS principle wherever possible. That means doing my homework 1st. Sorry if this is the wrong place to ask, but you seem to have worked around a lot of the challenges of an Electra Cruiser build. I have good basic bike build knowledge but not a full machine shop at my fingertips, so would like to keep it simple. Any advice appreciated! Thanks!

I will be installing a BBS02 shortly in an alloy Electra Cruiser 3 shortly. (1) I too am expecting the BBS02 to install without frame modification, but can't confirm that yet. (2) Those stacked battery racks are on eBay anytime; with and without battery. (3) No experience with the SRAM chain, but my first E-bike with BBS01 was a Shimano 7spd and that chain works fine with the stock Bafang chain ring and the 42T Lekkie (better chain line). I'm "guessing" the 7spd chains are similar design (?). (4) I suspect the BB on calfee20's Electra Lux fat is wider than the BB on the bike your are considering and the male version I am using. Mine has a standard 60-73mm BB that accepts a standard BBS02. (5) No experience with rim brakes and electric motor power and speeds, but others have said they are fine. I personally prefer hydraulic disc brakes, but most of my past is with MTB's.
Check out my build thread linked below. I am (along with calfee20's build knowledge) considering several different rear hubs from Sturmey-Archer. They make 3spd drum IGH's that fit the frame. The outside of the rear on my cruiser measures exactly 135mm, so bolting on a pair of Paragon sliding dropouts on the 'outside" of the rear will allow 135mm rear IGH hubs to be used. With that said, there is no real need to change out your 7spd rim brake setup if you are happy with the braking. Although as calfee20 points out, moving the rear axle back using Paragon dropouts will allow a battery mounting location down low behind the set tube putting that weight low and centered.
KISS is good and I bet you will get a big one from the bride when it is done! ;-)Last edited by Rider; 06-08-2017, 06:22 AM. -
Thanks for the great feedback Rider...one issue I have come across, doners I'm looking at are Electra Cruiser Step Thru 7d's (w/ 7 speed derailleur), thought they were SRAM but now realize it's a Shimano w/ Twist grip so s/b a Shimano derailleur, so should play OK with the Lekkie Bling ring...Whew!.... Buuuuttttt.... looks like they still have the old school 1 piece "ashtabulah" style crankarm/bottom bearing and that probably means a press fit bearing cup needs to be yanked and swapped...argh! Looks like the current 2017 spec Electra 7d has finally gotten into the 20th century with a 3 piece crank, which should be on a 68MM BB ...that would be a clean and sweet swap. I'm trying to keep the cost down with a used frame (why buy new and void a warranty?)...so more work if it has the 1 piece but sounds like the chain ring alignment should be close to OK using the Lekkie (or Bafang) chain ring. Think I saw someplace the Lekkie has an 11MM offset dish, any clue where the chain ring sits on the BBS02 in relation to the "standard" chain ring alignment? Didn't see a profile of the motor on the website, still worried about both a chain alignment offset and frame conflict with the gear housing but getting closer to figuring it out.
Also, looks like the 7d is an aluminum alloy frame so VIP to get a neat fit and avoid bending, cutting or dimpling if possible.
As for brakes, agree, hydraulic brakes would be great...but they don't seem to be in the playbook for the beach cruisers...V brakes are standard on the 7d's, and on an alloy frame probably not an option to add a disc brake hanger on both a technical or budget basis. As long as the V-brake will lock up with the added load, I think they will do the job.
As for the battery, thanks for feedback on the alternatives want to get a quality build Japanese or Korean bat, sounds like there is a lot of junk out there surprised I don't see a rear rack design on the Luna website..... thanks for the help and feedback!
I DO like the idea of pushing back the rear wheel enough to stuff a 52v mighty mini behind the seatpost...but the cost for the SA hub, & re building the wheel and new dropouts just to downgrade to a 3sp from a 7sp would probably pay for the higher amp flat rack battery I am considering...but that is a great idea! Let me know how it fits!
Thanks for the link to your build too. Will post a build thread if I can get this all figured out!Last edited by thedadude; 06-08-2017, 08:21 PM.

Sorry I didn't get back to you. I thought Rider was answering questions but realized I should answer a few.Originally posted by thedadude View Post
The battery was bought from Luna and they do not carry it anymore so that was a dead end for me. If I had it to do over I would put some kind of a rectangle on top of the motor and against the seat tube.
I was going to copy spinningmagnets build but this standard cruiser fell in my lap so the motor shaft was too long. The spacer was needed.
The Luna Eclipse will give you a great chain line but there are some chains it won't work with. I should start a thread on this but I have been lazy.
Rim brakes are fine and I hear the cool stop pads are very good.
For advice ...........get the biggest battery you can afford. You can not estimate how much you will use this before you have one. I have a 24 amp/hr triangle now and it really is the most wonderful thing.Comment

Just gave thedadude my limited knowledge input, which may vary from more knowledgeable others... Only you can answer questions about your build itself. ;-)
Help when I can. Learn when I can't. I don't work for this sight or Luna, so my thoughts are definitely my own. I sure appreciate the knowledge this site provides and sharing is the best way to get good information out there.Last edited by Rider; 06-13-2017, 03:35 AM.
