Unfortunately Schwalbe does not make a tire compatible with my rims. The best fit is 20x4” with a range of 3-4.5”.

Thank you for your very clear explanation. I expect it will save me some serious money. I plan to swap out my three aggressive knobbies for smoother and higher pressure 20X4” or slightly fatter road tires for touring on my full suspension recumbent etrike. Of course that requires persuading my...

Is the TPI count for a bike tire an important factor to consider when choosing tires? In what way does the TPI count affect a tires performance? It certainly correlates with the price of a tire so I assume it is a measure of quality in some way.

I’ve been trying different profiles for my BBSHD 1000W motor and 48V battery mounted on a Sunseeker Fat Tad. The throttle seems to have more limited power impact than it did with the stock profile, but it isn’t obvious to me whigh setting changes gave caused that. Which settings in a profile can...

Okay then. I’ve come up with a way to trick the wheel speed sensor. Gimmicky but I think it will work. I’ll use my old record turntable at 33 rpm with one or more magnets on the platen to emulate a speed of 10-12 mph. I’ll simply use some machining dial mounts to suspend the sensor over the...

A snag arose with my trying to strobe the chain ring. Without a moving input to the speed sensor an error is thrown. So ideally I would like to disable that input so I can proceed with the Speed% maximum test with the strobe and then check the assist Speed% for each PAS level. My stock...

Al, thank you for the very appropriate suggestion. Being new to posting on any forum it is taking me a while to get things put where they make the most sense. I simply reposted my initial thoughts since I had no clue how I might move them. Best regards, Duncan

This is being reposted here at the suggestion of Al Hicks since the discussions here are more specific to the Bafang motors. I am gradually gaining a firmer toe hold on programming the controller for my Bafang BBSHD 1000 Watt using a 48 Volt battery. My current understanding is that the Speed%...

I am gradually gaining a firmer toe hold on programming the controller for my Bafang BBSHD 1000 Watt using a 48 Volt battery. My current understanding is that the Speed% is a setting for the chain ring rpm (motor rpm) after which assist basically stops. Apparently the maximum rotational speed is...

Very nice bike. Tidy, modestly equipped and easy to climb onto. Must be quite comfortable with that top dollar seat post when running lower tire pressures.

Thanks Al. I’ve already asked my Chinese electrical engineer with many contacts overseas to explore contacting Bafang. Within the company there must be documentation of the controller parameters at least in Chinese. If anyone can tease that out he can and then shed some light on what the...

Understood and thanks. Now another question. I read somewhere that the current% setting is actually an assist limit based on road speed. That doesn’t make any sense to me. My understanding is that it relates to the amount of assist (torque) the motor supplies which with an electric motor should...

When looking over the stock and various .el’s available a question arose. Why are there speed limitations on the 5 or 9 PAS levels. If I am using a derailleur to maintain my cadence at a specific PAS setting what purpose does limiting my speed serve? I’m using a FatTad with a Bafang BBSHD 1000...
