99t4- yes, plugs under the fluffy headset would probably be more effective. You of course described the problem correctly. There's a reason why outdoor mics are covered in thick fluff. If I do resort to a helmet, I will at least not have to be concerned about a hairstyle problem... And always...

Let's not get our knickers in a twist guys. I said 60mph "capable". I may open it up for 10 or 15 seconds once or twice a ride in a straight line on level terrain. Not much hysteresis. Good quality tires with excellent tread, properly inflated. It's not like I'm at sustained speeds cornering up...

Yes, note my reference to CatEars in second paragraph above, but thanks for the link to the other thread. I had not done any search on the topic here. My simple design of course works without a helmet and is faster to put on, more hygenic, and more effective than earplugs- which are a PITA...

I don't know about you, but if I'm (routinely) exceeding 30 mph on an ebike I find wind noise extremely unpleasant. Indeed hearing damage can occur above that speed. I always wear earplugs for shop work, but they're ineffective at killing wind noise, which is transmitted right through them by...

2Phast- I did the mod in question to my Mongoose Pug build in the ebike build section here. It's not easy and ideally requires a lathe, and accurate TIG work. It turned out well and I have a lot of miles on it. The description starts at post #20...

Good one :). I'll drop the price to $300 shipped in the lower 48 if anyone's interested.

I did use it on one of my custom ebike builds. It was difficult to program controllers to run it perfectly- there are no Hall sensors. If you're a VESC expert, give it a shot... the power to weight ratio is very good. Cooling is absolutely not a concern unless it was going to be fully enclosed.

Thanks guys. It's a fun retirement hobby, since lithium cells, specialized motors and controllers have become a thing in the last decade. When I was a kid it was just mini bikes or mx bikes, and annoyed neighbors would occasionally call the cops... so silence is golden. Plus these don't directly...

Ok.......... the last 3 comments either didn't make much sense, or were not helpful, to anyone. This build, my 5th, exceeds the performance of almost all street ebikes out there, custom or otherwise, and required a considerable skill set to execute. That should speak for itself.

Very professional looking job, and a fine example of high dollar cnc/bolt together construction. I'd move this to the motorcycles section though.

MOK- suspension was all promptly fixed up as per previous posts. I am still getting a single rattle out of the fork over sharper bumps that I can't pinpoint. I think the fork is topping out. It's not the headset. (Edit- turns out it was the battery pack making occasional noise against the top...

You're correct to assume I'm strictly a DIY builder. When i was younger i built 3 different recumbent bikes from scratch, then years later designed and built a run of a dozen full suspension mtb frames from 7005 Easton aluminum tubing, including fabricating a large 500F oven to heat treat them...

Battery is finished and installed, with double paired zip ties to aluminum brackets at the front and a rubber covered U bolt at the rear. It's on a new 84V 5A charger for the first time. Every parallel group is dead even and rising nicely. Will be test riding shortly. The extra 21V over the 15s...

eMark- the green Orange County Choppers Schwinn is an unusual frame design that lent itself to the low battery/motor/controller mounting setup. My 4 other builds all required putting the battery pack on the top tubes as they wont fit inside the triangle. They all handle great, the mass (12- 16...

Pretty much done. Just need to drill 4 holes in the base for mounting on the bike, and have to solder up an adapter plug for the charger to QS8. Anyone know whether amp output is adjustable on this charger? Voltage is, but current probably not... (edit- the current can be adjusted but it's...
