Hub or Mid-Drive?

MOST chargers charge to 85-90% by default


If you want to verify the final charge state from your charger, it will usually be listed on the charger. A 100% charge is generally 4.2 volts times the number of cells in series. So for a "48v" battery a 100% charge is 54.6 volts.

Upgrade your sprocket and chain on a mid drive. Less maintainance. Tap brake when shifting, less stress on parts. Well programmed BBSO2 is not just transportation, but fun to ride. I would definitely have front suspension minimum on whatever your choice

You may not have steep hills, but some days the wind might be blowing hard in your face...having some power in reserve is a good thing. I think the mid-drive will be more efficient over a wider speed range. You have to keep you speed up on hub motors on hills or you may over heat.

Changing tires like you mention will "probably" happen a lot more often than changing sprockets. Changing a tire on a mid drive is just like a "normal" bike.

I just got a ready made BBS02 mid drive bike for under 2K, and I just love it. I'm also quite sure it will take you your MAX. estimated range with out problem, battery wise.

Under 2K and is a quality bike too, I wrote a bit of a review with a full size pic. of "my" bike on my metal detecting website, which is my other hobby.

Good luck with your decision, it took me a long time as there are sooo many models to choose from.

Rick, thanks for commenting. And from a spot adjacent to the Bay of Fundy up in Nova Scotia, too! That tells me your bike is seeing some challenging conditions. I had previously watched Court's reviews of the Stunners; it was helpful to hear from an owner who's made serious use of them, too. Thanks again.
 
Jack, THANK YOU. And if you watched Court's video you saw how it got up to 20mph in about 5 seconds, just like advertised, and you noticed that court didn't have to do ANY shifting. Noticed one poster on this thread said a hub would get to speed quicker than a mid drive, while at the same time said a mid drive would have more hill climbing power, does not make any sense, power is power.

And I'll stand by my statement that the mid drive will be more efficient over a wider speed range.

By the way I priced the rear freewheel (sprocket cluster) and you can get the exact same MF-TZ21 delivered for less than 20 US dollars here.

So that is really a non issue for me, should I ever actually wear one out, in fact for the price I'm going to just get a spare to have on hand, a spare chain too maybe.

For day in day out reliability and efficiency, can't beat a direct drive hub drive. I suppose the Bosch mid drive is reliable, but it is also very expensive. Those BBS middrives have a checkered history.. Just search in ES or here... Maybe they will evolve to be as reliable.

DD Hubs really have very few moving parts, no gears and tens of millions are sold every year..

As far as efficiency, just dial down the pedal assist and you'll go far.. I've gotten 40 miles on 390Wh on a DD hub motor.... You can order a bike with a larger battery and be done with any range issues.

Feel free to be sure, but you are so wrong! Hill climbing is TORQUE, top speed is POWER, and never the twain shall meet. ;)
Same on motorcycles, cars, trucks and anything else with a motor.
Hub motors vastly faster on the road. Mid drives vastly superior in climbing. Both could have the same hp ratings.
My Haibike Mid rarely to NEVER shows its real power (climbing ability) on my flat rides in the midwest. It's hugely SLOWER than my Falco hub drive trike or the Stromer hub drive bike I sold. Yet it will climb hills that the hub motors can't touch.
No, power is NOT power.

Power (HP=TORQUE X RPM) mince words all you want to be right.

Watt for Watt which is just another word / measurement for power you can go the same speed, we're only aloud to go 20. 500 watts is 500 watts, so yes power is power, being able to change gears just makes a better , more efficient machine, don't see many cars or motorcycles with just one speed / gear. I'm done arguing. Oh yeah I've been to ES.
