Awesome bike!
I vote uni colour with a rusty "fake" tank. Or a wooden tank. :thumbsup:
Or some wooden details. With that colour gives it that Surf Woody Wagon look.

In the end, what you like is most important.

Great work. It was fun to catch up on your progress and see that you have it rideable now. Killer build.
I hope to see it when I am in your town next month.

Awesome looking bike! Will look fantastic with either the red rims or the mono scheme. What about a beige or white color wheel?
My plan is to go for 26x3 rear tire and 26x2.35 front one, i am thinking about Project 346 Balloon, since they are just so great and retro looking. There is not really a lot of choice for good quality white or creme tires in this size. If something nice comes up i might still change my mind.

Careful, Bart, all the cool parts might disappear from your town! King is known to score...

I wonder if I can find a suitcase big enough to fit the Firebolt into? :D :D

Made my speedometer work by attaching a bigger magnet :) Because the chain stays are wide, the sensor just was too far away to pick the magnet, that's why it didn't work before. And done a 10km test run through the town. Feels good, the bike is definitely alive. Maxed at 35 kmph, about 21.5 mph. Not much faster then i usually go, but so effortless. Surely when i put a smaller sprocket on the back and/or bigger on the front and swap the rear hub out for Nuvinci, the bike would both be more comfortable to ride and more smooth. And, well, probably faster, though i don't really feel the urge to go much faster than that. That speed is just perfect for me to be able to control the traffic and street situation, for the brakes to easily slow the bike down without slipping and also for the suspension to absorb all the imperfections.

Now is the time of rather minor updates rather then major ones, but i want to set it up straight before i take it apart again and finish the frame up.
After burning a few bulbs (my actual output voltage is 6,4 instead of 6, too much for vintage ones) and sacrificing a LED lamp for parts i have finally made a light work. I've put a modern bulb into a NOS vintage dynamo lamp body i've got from my friend in Amsterdam around 7 years ago. It is probably temporary, since it looks too small on this bike, and even though i love it i may change it later. But at least i now have any light at all, so i am street legal :)
I've taken the bike out for a third ride, went to the distant neighborhood of my town to visit my friends, so it is now 20km more on it. I've hit the top speed of 46 kmph on it going downhill.

During the ride i had to tense up my chain once, and then half way there i've started hearing bad brake noises while i was rolling. The noise did stop once i was braking, so i figured it is because the brake was unaligned to the wheel. When tightening the axle i felt that i've destroyed the threads on the left nut, but it was too late to return. So i've finished the ride with a bit of stress for my bike falling apart and brake failing (did i mention it was heating up quite a lot more then i consider safe?) but without any unhappy incidents :D
Once home i've immediately decided to take the wheel i was using off and leave it for some non-electric project. Luckily the Nuvinci N380 hub i've ordered earlier have already came a few days ago. Since i only have money for good deals not for bad ones, i managed to buy it pretty cheaply from some warehouse who had old stock of complete new wheels with this hub. So i went ahead and decided to put the whole wheel in now for a test. It is 28" wheel, i am using 28x2.0 Continental tire with it. I am also upgrading it from no brake to roller brake using a special Nuvinci brake adapter tool i've bought from US a couple of month ago.

That's just amazing with those hubs that you can simply swap the brake adapter from roller to disc or to none for using with v-brakes! Not like with Shimano, when you actually need to buy a different model hub and even some parts are not interchangeable. Pity they don't have a coaster version though, but it won't work for the e-bike well anyway i am afraid. Unlike this beautiful BR-IM81 roller brake i am planning to use :)
IMG_6727.JPG


The heating issues should be gone now with such a huge radiator. Here is the BR-IM41 i used to run before for comparison.

Another thing i've managed is the tensioning bolts. Since i don't have a lathe i've decided instead of cutting them down to drill and tap holes in the end of M10 bolts and insert some M6 ones in. Not perfectly straight and aligned obviously, but after some sanding they do the job well enough! And they definitely look better then my previous attempt to carefully cut one down with just basic tools. Of course if i wanted them well done i could invest a lot of my time and hand craft perfect bolts, file them and polish, but i am not a perfectionist and i just stick with the faster way :)
IMG_6729.JPG


That's how the bike looks now. I still need to put an extra washer on top of the brake in order for the dropout not to block the cable nut from activating the brake. And also to connect the shifter and shifting cables. You can totally see the 28" wheel is a bit too much for it, but it will do for the sake of tests. Once ive tried the transmission and brakes i can basically call it mostly finished and move on to frame refinement, cable guiding, little details like rear lights and display placement, painting and pre-final assembly.

Hello everyone, wish you guys happy new year!
Another year of working on this project :D I am paying it my time and attention, but unfortunately it doesn't go all that fast. And the fact there are problems appearing along the way doesn't help :)

First thing is i've put the rear wheel properly and again after fighting a bit with Nuvinci shifting interface made it work.
What has gone wrong: the shifting was a bit too stiff, i am not sure why, and during the test drive the shifter snapped off. I did not yet check how bad the damage is, hope it is not beyond repair. Possible reasons for that are cold weather outside or funny cable guidance.
IMG_6833.JPG


The front wheel is also installed and seems to work fine. I didn't re-solder the left braking lever yet, but i hope i am smart enough not to engage the front brake alone while the engine is active.
IMG_6834.JPG


I've added a mirror and swapped the grips for another temporary option for some comfort.
IMG_6835.JPG


And then surprise! My display started to act weird. It does not show the battery level and speed. The battery itself shows the charge is full and the speed sensor works fine. How do i know it? During the test ride it suddenly activated and acted normally for a few minutes, and then froze again, showing the speed different then zero but not updating it. The bike is fully functional despite this issue, but i have to fix it somehow. Reading forums i've found a few more people had this or similar issue, usually it means some wire connection is not stable. Not too nice :/
IMG_6840.JPG


Another sad piece of news, on the way back home i've torn my persons seat a little. I am not used to the size of that thing, and the seat happened to be exactly on the level of the door lock, so when i was guiding the bike to the yard i've damaged it. It was not perfect anyway, but good enough for me not to have to reupholster it. Now it seems to not be an oprion any more, so i'd have to fix it.
IMG_6839.JPG


Then come the rims. I got them to the local powdercoating shop recently, asking them to make a red metallic finish. I've already had a bike and a few things done by the guys and i trust them. Though the quality is really okay, i am unhappy with the color :/ Paid them 60 bucks, not too cheap for a pair of rims in my area. Now i'd have to overpaint them probably, since removing powder could thinner the aluminium of the rim. So more money to spend. I wanted it to me more candy paint looking, like the previous bike they've done for me, and it looks more like a toy now. I know it is completely my fault that i didn't make sure they do it exactly the color i want, so no claims to the guys at the service, they've done their job well.
IMG_6848.JPG


I also bought a pair of Electra grips recently that i may want to use with the build. It is also not exactly the color i saw on the photo, but at least way closer, so i may end up using them or may not.
IMG_6885.JPG


These are the news for now, seems i am not going to finish assembly and tests as soon as i wanted to. I now have a few issues to go through and some more money to spend to fix them. But i keep going and i still hope the bike will be ready for the spring season ;)

I do like the colour on your rims!

I can't judge the money/quality thing on your rims, but there is a powdercoating and steel company near my house that sand blasts and powdercoats a frame + fork for 60 euros. (all RAL classic colours, depending if they have that colour in stock). If I can help or assist you with that.

I like that yellow front wheel as wel :cool:

Is another hub an option for you? A singlespeed electric bike for simplicity?

You got an great lookin' bike there at least.
