I use the Ortlieb Office Bag for commuting. It is 15.7"w x 11.8"h x 6.7"d. However, the top rolls and the sides are flexible, so your briefcase should fit. I usually carry two laptops and have stuffed it pretty full when I got Amazon deliveries to my work that I had to get home. It is waterproof and...

You could improve it by installing a lithium battery instead of lead acid. That would cost more money than I would spend on this bike. I am not sure about the tires. Are those 16" rims?

Are you wanting to restore this as a collector? Otherwise, I think you would get a more functional e-bike by buying a hub motor kit from eBay and a used mountain bike from Craigslist than putting time and money into this project.

Maybe the Nitto Bosco:

If your bike uses a quill stem, the Nitto Dirt Drop will bring it up really high.

I bought the Nitto Albatross bar for my build, but they swept back too far for me. https://cdn.shopify.com/s/files/1/1403/7343/products/handlebar-alba-cromo-4_1600x.jpg?v=1549061016 I ended up getting the Jones Loop SG 2.5. It only has 2.5" of rise, but I also used a lot of spacers on the stem to li...

Thanks. I might look into getting one then.

Interesting. Do you think a 3D printer is a useful tool or is it more of a hobby and you have to actively look for projects that you can use it for? I can think of a couple of times in the past year it might have been handy to have one, but I was able to find another solution.

As long as the frame has the clearance the 700c wheel should work fine. It is hard to tell from that picture if the frame and the hub have a mount for a rear disc brake.

While bad accidents can occur on a wide open highway with a bike lane, I think the biggest risk to cyclists is at intersections and driveways. At least that is where I have been hit by cars or have had to take evasive actions. I agree with wturber that cars aren't going away soon particularly in the...

I think Makita did have a balance/BMS problem with their batteries in the past. I only have the newer Star batteries and haven't had a problem with them in the three years I have had them. When I researched it, Makita and DeWalt were the top choices for contractors. DeWalt was more popular, but Maki...

I paid $25 for 10 25g cartridges from Amazon. I have wide, but not fat, tires and 12g is not quite enough to fill them. I haven't had a flat in a couple of years and my current work assignment is home based, so those 10 cartridges should last for a while. That 18v pump looks interesting. I gave my d...

The brakes on that bike will work fine at the speeds a 250 watt motor will drive you.

That bottle seems like more trouble than it is worth. I carry two of the 25g CO2 cartridges. They are small and easy to carry. CO2 does leak out faster than air, but they will get me home if I get a flat and then I replace the air with a hand pump at home. I do have a small compressor at home that I...

You measure the spoke from the inside of the elbow to the end of the thread. Spoke lengths are usually described in mm.

National Parks may open up trails to e-bikes:

No I didn't. Seems like of you mounted the battery that way there'd be a lot of stress on the locking pin whereas the plastic frame takes it all when mounted nose up. I don't have personal experience with one, but the Luna Wolfpack uses a magnetic mount and doesn't clip in like a shark enclosure do...

hm.. know any good references for tektro brake-hose matching? i tried this before with a tektro set and couldn't find right spec hose to match it (hence the rear brake on my bike is a normal mechanical ebrake). i still have the tektro bleed kit so would be interested in trying this out :) Tektro is...

Secondly... Regarding batteries. Can two large em3ev batteries be paired to function as one page battery? Or would it be safer to manually switch to the alternate battery? Yes, as long as you charge them to the exact same voltage before connecting them. Thirdly ... Extra long length hydraulic disc ...

Maybe something like this would work:

If you are more specific about what you want measured beyond the measurements provided by EM3EV, I can do that. When I bought mine a few months ago, they had a template on their website you could print, cut out, and tape the pages together. I can't find it on my computer or their website, but if you...

They had a template you could print out on their website when I bought mine, but I can't find it now. As for the connector, you can put an XT60 connector on it. That is what I intend to do with mine. Or you can just hardwire the mounting bracket to the controller. It came with some bullet connectors...

The Eggrider works with the KT protocol, so I doubt it would work with a Grin controller. You would need to get a KT controller. Or you could buy a Cycle Analyst display instead. Lots of non-ebikes have displays for speed, distance, cadence, etc. I don't think it would call attention to you.

That was a lot of work. I am sure you will get it tuned the way you want it in the next couple of weeks.

*shrug* This is what i ride. 16" up front, 20" out back. It gets compliments constantly. I even had this crappy folding bike at one point with dual 20" wheels ( i had some fat 20 x 2.3 tires installed ).. it also got compliments constantly. I don't think small wheels are a big deal for anyone other...
