    Adding tail lights to E bike

    When I put lights on my E-bike, I just made sure to get ones with variable input voltages. As I recall, my tail light is variable from 6-60 V, which works fine for my 52 V system. Then I can just splice the two wires into a 5.5 x 2.1 mm round connector and plug directly into my CA3. Biggest...

    Best and Coolest HELMET BRANDS for COMMUTING..?

    If it's on IndieGoGo, it's overpriced and a long, long way off from delivery. Order it now and you might get it in time to use it late this summer.

    Throttle or no throttle. That is the question

    My bike does have a throttle, which I've only used occasionally until the past week. On my route out to the golf course, there is construction on one of the roads, so they put in a traffic light and it's single lane with no shoulders or sidewalks. Apart from the main highway with semi's about 3...

    How skilled are you in fixing your ebike ?

    Having built a bike from components, I can fix pretty much anything. Problem is not much goes wrong on a bike to fix. Even after a couple of crashes, I find that I need more fixing than the bike does. If you have a front derailleur, then you'll always be fiddling with it, but if you've gone to a...

    going from 40t to 42t

    You probably cannot go much larger when you use individual rings. I was able to go 42T front but ran into problems at 44T with a chainring that bolts onto the crankset. The trick is to buy an integrated crank arm and chainring set. The advantage of the integrated set is that the chainring is...

    Reducing Weight on Arthritic Hands

    Oh, and the CBD I use comes from a hemp plant. The stuff they make rope and t-shirts out of. You can also buy it at the health food store as Hemp Hearts, but I don't recommend that unless you want to be extremely regular.

    Reducing Weight on Arthritic Hands

    I never have ingested it. I simply use it as a topical. Just apply whatever is on the dropper to your skin in the affected area, typically a joint and rub it in. The Bio-freeze also helps alleviate the pain, but anything like Rub A535 or similar product would work as well. The funny thing about...

    Reducing Weight on Arthritic Hands

    Why don't you try something to reduce the pain of arthritis? I had arthritic pain in my thumbs so bad that in the summer of 2019, I couldn't even hold a golf club and had to give up golf. Cortisone shots helped a bit, but the period of relief got less and less with each round of injections...

    Nearly finished a custom GMAC DIY

    I've got almost 1200 km on this bike since March, mostly just back and forth to the golf course. At 25 km per trip, that's almost 48 rounds of golf, though there was some practice time in there too. So far no complaints about the bike, BUT, I got another flat tire, on the back, of course, for...

    Nearly finished a custom GMAC DIY

    I got the 10T winding and I did have to install a new chain for the 48T front ring.

    Best and Coolest HELMET BRANDS for COMMUTING..?

    I just got my Lumos Ultra helmet and you can tell it's a much beefier helmet than what I had on the road bike. I love the flashing lights front and back. It came with a remote for signals but I've never used it. I think motorists respond more to hand signals than signal lights on your helmet. I...

    Help/Advice - (Ecotric) Throttle Speed is Determined by PAS???

    I have a GMAC hub motor with PAS and throttle. Once, early on I screwed up the programming and got the throttle tied to the PAS level and didn't like it. Just fiddle with the programming till the throttle is independent of the PAS. It may involve a bit of trial and error, but isn't that the...

    How to Live with Throttle-only Riding?

    I suggest you learn how to do it yourself, so you won't be at the mercy of the LBS. In all likelihood, their techs are also learning how to do it themselves. PAS units are not expensive. Just swap in a new one and be done with it. Riding an extended period on throttle alone is a PITT. Do it all...

    Full Suspension Vs. Seatpost Suspension...which is best?

    I've got a hardtail with the Satori Animaris seatpost, which I prefer to the Suntour NCX and the Ergon E-Mtb seat (preference over the Brooks B17). Before I went with the hardtail, I looked at FS bikes quite a bit and didn't find any that would fit my battery. Typically on a FS bike frame, the...

    going from 40t to 42t

    That's interesting, because I just went the other way and changed out a 42T front for a 48T and I love the bigger ring on the front. With the 42T, I was only using 3 or 4 of the smaller gears on the back (10 ring, 11-36T). With the 48T, I use 7 or 8 gears and only the 36T and the next smaller...

    mid drives are not for everyone/throttles are fine

    I've got a hub drive bike with a throttle, which I rarely use, but is really handy when you need it. I set my PAS to level 4 (out of 10) and after that, it's just shifting gears and my cadence never changes. Where the throttle is handy is when I have to go through a construction zone and one of...

    Reasons you ride? - Aside from the obvious reason where riding is your passion.

    I built my E-bike simply to ride out to the golf course and get some excercise. My knees won't allow me to walk the course anymore, but cycling doesn't bother them. And it feels really good to be able to pass a group of roadies on a hill and call out "coming up on your left". I don't hang around...

    Chain ring too close to frame

    This is the main reason I built my own bike. I want to be the guy responsible for something working (or not) because i can take pride from what I've done or learn from it and do it right the 2nd time. I never return parts except maybe to Amazon. It's just too much of a hassle. Since I started my...

    Chain ring too close to frame

    The bike is a DIY built on a GT Karakorum frame. I didn't choose the GT out of any preference. In Calgary in December, that's what was available in my budget. it's a 29er with 2.3" tires and I found that with the 42T front, you can get pedaling so fast, you feel like you're out of balance. I...

    Chain ring too close to frame

    I used a SunLite dual chainguard crankset. The crankarm is permanently fixed to the crankarm but by doing that, they can get the chainline down to 45 mm. With my 104 BCD 42T ring I have to mount it on the inside of the crankarm with 2 spacers to get the chainline even close to 45 mm. With the...
