Cowardlyducks - E-BikeE builds

Been neglecting this thread a bit. As per the video below I'm building another BikeE for commuting. I'll try and put more details about it in this thread, but for now enjoy this little exploration of all the 3D printed parts on my BikeE!

Here's a few teaser shots of the new BikeE I'll be converting this year:

The loose plan at this stage is to install front suspension, have a Schlumpf speed drive installed by a local bike shop, build some custom battery boxes to sit on the rear panniers and install about 2Kwh of pouch cells.
Motor is a 9C from Grin and controller is a phase runner.
I'll also put a solar panel up front eventually, so it will be fairly similar to my existing BikeE, but with suspension and way more range. The motor is a slightly lower Kv, so top speed will also be slightly reduced, but only by around 5kph...although with the added weight, and semi-knobbly tires maybe more.
I hope to be able to take this bike to more off-road places. Nothing too crazy, but certainly fire trails and smooth single track would be nice.

I haven't firmly decided on the front wheel size yet. The fork I have on order is for a 20" wheel, but I might still run a 16" with disc brake to keep the fork flop low and geometry decent. I will probably use a 2-3 inch tire though so it won't be that much smaller.

Cheers
 
Right on! Looking forward to seeing the details on the front suspension conversion on the BikeE. I've seen it done: https://endless-sphere.com/forums/viewtopic.php?t=106520#p1561615

Thanks! Yes that thread was one I reviewed closely prior to taking the plunge. I'm not going that route however as I'm not interested in spacing out, or bending my cranks like that.
Instead I've managed to source a center suspended 20" fork. It doesn't have much travel (some is better than none), but will do the job nicely without having to mess with anything else....in theory.

I have what is probably the only Bike E AT in Tasmania and have been thinking about turning it into an EbikeE. I will be watching your work with interest!

Welcome to the forum AntC46! And glad to meet another AT owner in Australia...I don't know of any others!

The AT build is still coming along slowly, but I've got some other projects atm that have to take priority. I post a bit more frequently on the BikeE facebook page which I would suggest joining if not already: https://www.facebook.com/groups/165756106813440

For idea's regarding electric conversion I suggest reading back through this thread. Many of the things I did on my CT would also work on an AT, except the internal battery. I am also making a build video on the AT conversion which will cover most of the details...subscribe to my youtube if you're keen not to miss that: https://www.youtube.com/c/EbikeGarage/videos

Cheers
 
Thanks for the welcome. Yes, I have subscribed to your YouTube channel but I am somewhat annoyed with Facebook so I closed down my account some time ago. That's OK, I am reading your commuter Bike E build again for ideas / guidance while checking out my AT to see just how decrepit it is. It will be a little while before I can start - and I will be interested to see your solution for battery carrying.
 
Needed a break from building the red BikeE AT so I did a major overdue service on the blue CT.
Brakes, chain, rear freewheel all have over 7000km on them with the rear tire having over 3000km.
My motor hasn't been opened in over 15000km, and after cleaning it up from the Ferro Fluid I added, it looks pretty good.
The bike now has a total of over 25000km on it since being converted to electric. I'm loving how robust it's been...far more reliable than any other electric bike I've ever owned!

New brake pads are coolstop which should do nicely, although I don't really need the extra braking force when combined with regen braking.

I also added some Tanus Armor to the rear tire as can be seen in the photo above. This made installing the rear tire hugely painful and difficult, but a combination of brute force, patience and many metal tyre levers resulting in it being mounted with almost no damage.
This should mean I can run the rear as low as 20PSI for some better bump compliance. I might try 25PSI first though...last thing I want is rim dents or bead separation.

At some point in the next few years I'll also have to do something about the battery. It's only giving at most around 14AH now and has over 500 cycles. It's on it's last legs, but I may not need to replace it if I can parallel it with something external, at least to delay it's demise a bit longer. That being said, I only need around 10AH for my regular commute, so it should last at least another year, and potentially a whole lot longer if I stop using it over the Red AT.

Cheers
 
Never did like the e-bikeE frame much but i'm warming up to it. Looks strong and no sway. Maybe work in other recumbent designs.

Great builds. Like all the miles your getting.
 
I have one and think it's a pretty darn good design!

They push tubes (round is strong) and square tubing. If you think about it that frame should be easy to mount to, nice and tall.
Wonder how it resist twisting? Think about a trike with front A-arm suspension and the rear would be easy too.

No shortage of range there CD :lowbatt: :lol:
Agree!
I'm not quite sure how efficient this thing will be, but if it can manage around 12-15Wh/Km like my other BikeE it should make 130-150km of range doable at a decent speed.
If I take it slower and contribute more I could see it getting over 200km. :D

Cheers
 
second that motion, that big batteries go with recumbents. A little peddling and the world is your oyster.

Yup. Recumbent and big battery are like peanut butter and jelly.
 
That's a very nice battery box.. i need something similar to that for all my recumbents!
 
Thanks guys!
Yeah I'm estimating around 250km range when riding economically on this thing.

The box has to be tough as I plan on taking this thing off-road and it will get impacted by rocks, roots, etc.

Took it out for a maiden test ride the other day with things very dodgily setup. All I can say is to repeat something I previously said when I first built my blue CT many years ago...

Nearly identical experience. That might change a bit once I load it all up with all the other gear which will add quite a bit of weight, but it still has a whole lot more go than I expected that's for sure!

Cheers
