Re: Cyclist spits at me and makes a buzzing noise !

You could speed ahead of them, on a really fast bike, then drop the tacks. But not if you expect to see them again at a stop light. Come on Dan, don't give the jerks any ideas. tacks aren't particular about whose tires they flatten. A few years ago I was on a charity ride where someone had thrown o...

Re: hybrid power w charging via regen brakes ?

My inclination is why charge the battery? In other words, when going on these out of the way spots, just use the gas engine wherever you don't need to run the quieter electric motor, and thus always save some battery to use when needed. Of course you could carry a small generator, but again, if you ...

Re: lifepo4 options?

I understand your concern about the Ping LiFePO4 packs, but I've used them for years with no problems. Some are over 5 years old and still performing good. The protection from the shrink wrap is adequate for normal handling, and as long as they aren't placed against anything sharp or against bolt he...

Re: Perfect especifications for hills

The problem with your information is that there is no way to know what actual grades one might encounter, even though the average is under 10%. I.e., very few climbs have a constant slope and will have places that are significantly steeper then the average. This is why I prefer a mid drive or crank ...

Re: Bagang bb02 on tern link folder

If you worry about too much power from a 750W 48V BBS02 you need to just get a programming cable and adjust the current, etc. to suit your riding style. On my trikes, both equipped with a 750W 48V BBS02 the max current is set at 15 amps and the PAS current percentages are at varying percentages betw...

Re: Definite guide to suppress BB creacking noise with mid drive kits

Good idea for a thread. I've had a BBS02 on my tadpole trike for over 4 years and over 3000 miles. Recently it started making that creaking noise you described and of course I ignored it for a while. The torque arm had loosened a bit and the BB nut had loosened. After fixing it all, including making...

Re: 2018 Kona Unit BBSHD Build with questions

I couldn't quite tell from the pictures, but be sure the motor is tight against the down tube. You can use a spacer if needed, such as a piece of hard rubber, etc. This will prevent any tendency for the motor to rock back and forth, which is what makes the big crank nut to come loose. Looks like a n...

Re: Need some guidance on watts up meter

In general, you got good advice, but for your application it may not be so good. You have to get access to the positive and negative wires that run between your battery and your controller. If your controller is located within the battery rack that may be very difficult or even impossible. Even if y...

Re: bafang motor with stabilizer bar - not so stable

Edit: Sorry, I reread your first post and you have pretty much done what I said. Perhaps a small block of hard rubber or some such item between the motor and the down tube would eliminate the tendency it has to apply too much torque for your brace to control. Since the motor's torque is towards the ...

Nice find. I guess it sort of does what the "O" ring solution does. Been too busy with other projects to spend any time working on the trike, but am anxious to "eliminate" the shimmy and will try one of these fixes soon. Thanks. :D

For starts on an uphill grade you need to be in your lowest gea...
