Re: Lightweight efficiency oriented BikeE conversion

So i've been thinking about this bike's front wheel and realized it could use an upgrade, just like the cannondale. I do believe i found the parts to do it. Gameplan: 20" stiff chromoly fork up front, and the tire will range from 20" x 1.5" to 18" x 1.5", all depending on how the bike handles the fr...

Re: Lightweight efficiency oriented BikeE conversion

Ah yeah, one of those. I bet you have the kind of whr/mi i could only dream of on my CLWBs. I do plan to throw fairings at both of mine to make up for the deficiency though. :mrgreen: Yeah that is another ballgame entirely. The hop and skip of the wheels is a thing that naturally happens on bikes wi...

Re: High performance & durability Cannondale Semi Recumbent

So i was browsing around for handlebar tubes and found out that rans sells one with an inner diameter of 1 1/8 inches, and outer diameter close enough to 1 1/4 in. that you can use 1 1/4in clamps. I gave rans a call and they were super super helpful and knowledgeable, as usual. :) So here's what we ...

Re: The holy grail for ebike wheels - 22 inch BMX rims = 18" motorcycle wheel diameter

Try looking for 19" BMX trials rims and tyres. I found that a winner. They are for people who hop up and down on the BMX balancing like a unicycle. Interesting. I'd never heard of these for pedalbikes until now. https://www.tartybikes.co.uk/19_inch_rims/c517.html Those rims seem to have an ERD gene...

Re: Hub motor industry dying?

That's a nice looking bike and I have had a few people stop me and give complements on the Brompton as well. However, there are definitely a lot of people out there that view small wheels as uncool and not just the spandex crowd. Personally, I see that as an impediment to widespread adoption, but c...

Re: Lightweight efficiency oriented BikeE conversion

From my frightening experiences in searching for the right weight balance on a recumbent, it was battery right below the seat that seemed to work best. To far forward or back, and it's really sketchy in bumpy and/or tight corners. That's what worked on my Bacchetta, but a long wheelbase may have ot...

Re: Hub motor industry dying?

I love my Brompton, but it would take a huge cultural change for small wheels to be popular in the United States for urban use just because of aesthetic reasons. They make the bike look out of proportion with the rider. They don't look cool. *shrug* This is what i ride. 16" up front, 20" out back. ...

Re: Lightweight efficiency oriented BikeE conversion

I've got the bike fully together, and must say that i really like how it rides. It's gentle even when you bang the poor 16 inch tire into a 2 inch dip, but you certainly feel it, but it's not the end of the world. One strange effect is that hits to the front wheel resonate across the frame. The bike...

I so love the ghetto ratchet strap em3ev battery mount. I just recently mounted one like that in an only slightly more sophisticated way. That is a hell of a lot of power on a roadbike. I'd love to see video of it, if you have the opportunity to show it. ..and interesting urban obstacles to deal wit...

Re: The holy grail for ebike wheels - 22 inch BMX rims = 18" motorcycle wheel diameter

Rix and I warned about this combo in the other thread .. if the tires go on the rim easily then also can come off easily, especially from a flat or impact, pothole, etc.. if it requires heavy duty metal tire levels to mount the tire then it will not likely unseat without those same tools.. Yeah, if...

Re: Lightweight efficiency oriented BikeE conversion

If you can find a nice big hill in your area it may be worth your time to figure out how well the bike handles at speed with different weights in different locations. I suspect that adding the battery directly over the front wheel might make a significant improvement. I basically live in the middle...

ppl I know that tried this almost died when their 18" moto tires came unseated from the 22" bike rims at speed.. so keep that in mind if you plan highway speeds on this setup.. its a loose fit and you need a wide rim..

Re: High performance & durability Cannondale Semi Recumbent

OK. I looked at a couple 18" moto tires already and it looks like the the outer diameter varies from 24.2" to 24.8" ( 2.25 - 3.0 size ). So actually the rear 18" moto easily equals a 24" bike size :bigthumb: So i do believe that the front/rear balance wont' be a problem on a 24"/20" equivalent wheel...

Re: Lightweight efficiency oriented BikeE conversion

What kind of battery setup do you plan for it? I found mounting mine on the rear tail as I did initially for a number of years somewhat ruined the handling leading to a number of unintended crashes and some complete flips off the back a few times. That's one of the main reasons I went with the inte...

The holy grail for ebike wheels - 22 inch BMX rims = 18" motorcycle wheel diameter

Recently when shopping for oddball wheel sizes for my recumbent, i stumbled upon 22 inch BMX rims , which recently came into fashion. As of writing, there are at least 4 manufacturers of these rims. Here's some examples: https://www.modernbike.com/22-inch-rims A few of these rims come in 457 ISO siz...

Re: High performance & durability Cannondale Semi Recumbent

Apparently there are two 22 inch bike rim types :lol:. I found a company that makes one in ISO 457. It's 36 holes and 1.5 inch wide. Effin' perfect for a 18 x 2.5" moto tire. https://www.modernbike.com/we-the-people-logic-22-welded-rim-36h-black According to kingfish, ISO 457 is the same as an 18" m...

Re: High performance & durability Cannondale Semi Recumbent

Looks to be in good condition! I like the high back also. I've been contemplating getting one of those for a while. You'll obviously want to change those tyres, they look original! My favourites are a Schwalbe Big Apple 16x2 on the front and a Maxxis M-Tread 20x2.1 on the rear. Although in my case ...

The bike E is no longer a pile of parts. They literally took every single part and mixed it into a bag, what a pain in the ass, especially the steering mechanism!! but it looks like it's worth it. cannondale-vs-bikee.jpg As you can see, the Bike E isn't much smaller than the cannondale, and the seat...

Re: Why would a controller cut out going uphill? (probably not battery related)

If the controller works with another battery, i don't think there is any problem with the controller at all. We can't blame the LVC of the controller because the other battery's voltage is higher. You've ruled out everything but the other battery. Unless the controller has a high voltage cutout, whi...

Turns out it's quite a rocket science to do it in a fashion where it still looks and behaves like a normal car. I don't doubt some people may have pulled that off, but it's quite an effort that shouldn't be toted around like it's nothing. There is no reason you can't make an electric car conversion...
