Re: E-bike or E-motorcycle?

This 28Mph e-conversion project was engineered with a focus on value, performance, and stealth. Glad you posted this. An e-trike was actually on my mind the more I thought about the build. I think it could be a good option in the winter due to the ability to add a large fairing to keep me warmer in...

Re: Old GT Full Suspension - The Perfect Road Build Platform?

Early to mid 2000's Giant Trance and Anthem's, Trek Fuel's, Kona Stinky's and Rocky Mountain Edge's and Slayer's are some of the best. Thanks for the link. My last bike was on a mid-2000s Trek Fuel frame. While better than most modern FS bikes, it still didn't have a ton of space. I'm not sure how ...

Re: eZee vs MAC? Your thoughts?

That's gonna be a big battery to hang on a seat post rack. Make sure you have a hell of a seat post, and a sturdy rack. Maybe do a custom job? I had a rack rated for 20lbs with a little 36v 12ah battery on it and it snapped after a couple months. I could only imagine your battery at Moab is going to...

Re: Is It OK To Leave The Bike Outside In Winter?

I'm so spoiled after living here over 20 years that below +18°C (64°F) gets a bit nippy at night and 22° or higher I turn on the fan, which is rarely used. During the day it gets few degrees warmer, but there's generally a breeze. Living in the tropics at altitude is hard to beat. The OP did say he...

Is It OK To Leave The Bike Outside In Winter?

I know it's bad to leave the battery out in the cold. Does it matter if you take the battery off of the bike each day and leave the bike itself out in an unheated garage, and in the morning bring the battery out, pop it on the bike, and go? I'm moving to a place without a heated place to store the b...

Re: Old GT Full Suspension - The Perfect Road Build Platform?

I don't have the GT yet, but getting a suitable frame is something I'm willing to invest my time and effort into. So far I'm at the stage of finding the best platform to build on(within reason, monetarily). Then I'll move onto the motor selection, figure out/build battery, and select controller. I'v...

Re: Old GT Full Suspension - The Perfect Road Build Platform?

Since the v-brake would only be in the rear, with a nice hydraulic disk front, I think it would be fine. A v-brake will easily lock a rear wheel if need be. It's hard for me to tell very well from the picture, but the Specialized seems like it might still have a fairly small main triangle. It might ...

Old GT Full Suspension - The Perfect Road Build Platform?

In my research/planning of a build to do ~35mph and long distances on bike paths, roads, and gravel rail-trails, it seems like one of these old GT full suspension bikes would be perfect. There's no need for long suspension travel if not off-roading, but I figure some rear suspension would be nice fo...

With modern bafang style mid-drives available, is there any benefit to using a hub motor as a mid-drive rather than one of those?

Re: Setting up dual drivetrain ebike

Did some more research and found this video of a guy who built a mid drive. He just takes off the fixed gear, leaves the freewheel on the other side attached to the pedals, and attaches a belt and pulley system to the other side to be powered by the motor. The motor doesn't spin the pedals even tho...

Re: Setting up dual drivetrain ebike

The benefit would be so that you can freewheel rather than being fixed gear all the time. It just seemed like it would be easier to weld a freewheel onto the motor shaft than to mess around with adapting the rear hub. Also, I just noticed I posted the same link twice. This is the one that says it wo...

Re: Denzel 72v 4-spd Gearbox Build 125cc Dual Sport

Newbie question here, but I'm trying to learn about a potential e-moto build and am very interested in a gearbox. If it has mega torque and rock crawler speeds in 1st and 2nd gear, and not a very high top speed, is there any reason to not change sprocket size to make it more usable in a street appli...

Re: Setting up dual drivetrain ebike

What about normal pedal drive-train on the right side as normal, motor on the left side. Freewheel on the normal drive side. Weld a 9t BMX freewheel to the motor shaft on the motor driven side. So it'll still be fixed in the rear, with the freewheeling on the motor shaft itself. That seems most simp...

I'm not really understanding the dual drive-train part. Could you explain more of the benefits you'd like out of the dual drive-train? What part of a standard set-up won't suit your needs, or needs to be different? Unless this is just for the sake of fun, which I totally get. I'm just not sure how i...

Re: speed traps

I agree with the above. If you're out on a straight with no one around, by all means hit the throttle. But you're probably not getting hit with a speeding ticket then. If there are people around or it's in town where there are intersections along the bike path(roads, paths, sidewalks, etc) then you ...

Huh. I think your last post just pretty much steered me toward the ebike. I do love to ride, enjoy the scenery, and stop to smell the roses when I feel like it.

Re: Bad suspension - poor design or just in disrepair?

I say just take it apart and see what you find. What's the harm? Have fun learning/tinkering and take it apart, clean it, and add fresh oil if it seems like everything is suitable. It could just be low on fluid. Put one end of the shock up and cycle it several times. Then turn it over the other way(...

What would you build for getting around a small city with pretty decent bike paths and a budget of ~$2,000? A nice, long range e-bike based on a full suspension MTB frame, or a motorcycle conversion, likely based on whatever cheap donor bike suits the needs? After a bit of reading, I'm surprised to ...

No reason for him to be passed since he lives in the states. 750 watt limit is good for more than 20 mph, a lot. You're certainly correct that 750w will get you over 20. My old 500w amazon bike kit would do 20. I miss that bike. Most places in the US have a speed limit too. I think ~15mph is common...

Re: Got fried by Col. Sanders today. eBike vs pedal

One simple solution(though not for a trike) would be to build a nice e-commuter from a touring bike platform. Something with drop bars and no more than 40mm wide tires. It won't be quite as fast as a full on race bike, but will be faster and more efficient than your often seen heavy, upright MTB pla...
