Define a good quality hard tail. How much does one of those cost new? Maybe a good example.
Pretty much bicycle store vs big box store.

Re: Shopping list

I found that one because it's a front and rear suspension bike the only thing I don't like so much is that $400 price tag. The wheel size doesn't matter too much to me but since the 26th is the most common I'll probably find a better deal on a motor if I get 26-in tires right? Anyway I would love m...

Ok so that frame would be ok but if I'm going to be doing regular fast riding I would need full suspension.

Re: raising voltage to maximize regen. braking?

Observed: comparing two battery packs, assuming the same voltage , higher parallelism (higher P number) means more capacity. More capacity means higher regen. current tolerance, which means more regen. power at that voltage, therefore better braking. But this higher capacity means more cells, and t...

Some 12 years later I am still riding the best 2 of them that had been mod a few times. The others had been sold and still riding. 2 is a good number.

Re: Slowest wind direct drive hub motor(s) available?

Nobody needs to actually put together an e-bike to know want they ultimately want for their own personal riding needs. A much better starting process in terms of time and efficiency would be to either borrow an ebike, rent an ebike or buy prebuilt e-bikes. Doing that is a whole bunch more efficient...

Re: Two battery packs- One for torque, one for speed

Maybe there's a combination that would give you both? Upping the voltage less dramatically may provide the torque boost you're looking for, and provide a speed increase. If you don't need the speed often, then field weakening can give you more speed on top of that. https://ebikes.ca/tools/simulator....

What about the gap between the magnets? You could analyze it forever and get a percentage point here or there. The bottom line, it doesnt matter! Just get out there and ride. Stop analyzing and make the purchases now. You may need to lower your expectations. Nothing I see in this thread indicates t...

Found the manual - 5 flashes is a bad throttle.
If you are running your throttle through your CA, I would check the connectors between the CA and controller first to make sure nothing is loose, rather than conclude it's the throttle itself.

Re: Shopping list

Preferred bike wheel size, or wheel size of bike you want to convert. Most common kits are for 26" wheels. Brake type of motor wheel. Disc or not. Rider weight. 160-200 pounds I would like to keep the price as low as reasonably possible but I will pay where I have to. Which of these cases for my ba...

Re: Shengyi X1 maximum phase current

I'd max it out. What is worst case if this is too much? The bike is adequate as is and wife wouldn't be happy if I mess it up. On other hand she'd be very happy with a little more acceleration from a stop light. I have an eZee front hub motor with baserunner L10 and 52v battery. Phase current at 80...

Thanks. My concern with the way mine appears to be working is that if I ever do charge to 100%, the charger would kick off before the battery reaches 58.8V and never balance.

Re: Shengyi X1 maximum phase current

Well 54.8 is closer to 55 than 54. Anyway, I'd max it out. Simulator shows a noticeable increase in torque (21%) up to 8mph, but not much difference after that. https://ebikes.ca/tools/simulator.html?motor=MDGWX&batt=B5216_GA&cont=cust_25_55_0.03_V&wheel=650b&hp=0&axis=mph&cont_b=cust_25_45_0.03_V&m...

Battery switched on or off during charging?

This seems odd to me, but maybe it's a simple explanation. My previous battery didn't have a switch. Separate charge and discharge connectors. My new battery also has separate charge and discharge connectors, but has an on/off switch as well. I usually check the charging progress by viewing the volt...
