    Ultra Chainring Swap?

    Should be good but would be nice to hear from Ana before ordering. Eyeballing it should have it missing a chain stay with very little room to spare. TBH this is a want and not a need. It's basically going to give me one more gear which I need because I have to pedal too fast in 9th gear over...

    Ultra Chainring Swap?

    The 48 T chainring is for fat tire bike only.. I need 48 T for e-mtb... I guess it's a different offset?

    Ultra Chainring Swap?

    Wow, thanks!... I was in contact with Anna Lee from greenbikekit who said she could get me one. I waited a month, emailed her and she said it got lost and she'd order another, that was another month ago.

    My ultra is no louder than the Yamaha PW motor on my Haibike, maybe even quieter

    Bafang M620 Ultra motor broken? Low torque problem. Best retailer for US?

    So if you've got a worn rotor gear you're basically screwed?

    How much difference do street tires make compared to knobbies

    Nothing I ride gets that sloppy. If it looks like that, I'm not riding through it!

    How much difference do street tires make compared to knobbies

    I hope I've made the right decision with the super moto X tires. My riding is mostly pavement but there's a 2 mi. stretch of dirt road I ride with hills that can stay wet long after a rain. The cheap kenda knobbies that came stock on the bike handle this with no problem whatsoever even as they...

    Bafang M620 Ultra motor broken? Low torque problem. Best retailer for US?

    I'd like to think I am easy on my Ultra so hoping for a long life. I had planned to open it up after just a couple hundred miles to re-lube but it's still quiet, maybe even quieter than when new. Maybe the grease guy was generous w/ mine but I'll have to take it apart this winter to check or...

    Bafang M620 Ultra motor broken? Low torque problem. Best retailer for US?

    I've read a fair amount of ultra motors needing replaced on this and other forums. Is there any sort of life expectancy for these motors? I've got a little over 1,000mi. on mine. Haven't opened it up yet as it's still very quiet

    How much difference do street tires make compared to knobbies

    Agreed, why my urban Rize RX came with knobbies is beyond me. I did ride it up and down the local ski hill trails. It's NOT a mountain bike

    How much difference do street tires make compared to knobbies

    I realize there's a thousand variables but when I switch to road tires from knobbies, how much more range can I expect, if any. I can go 40mi. now on a full charge. Going from cheap Kenda knobbies to Schwalbe MotoX tires is the plan. I'm hoping for a mile or two more range since the tires should...

    ebikes and headwinds

    That's a shame because all those extra electrons weigh a lot and slowed you down

    ebikes and headwinds

    How much did the Moto X tires increase your range? I'm expecting maybe a mile or two from my normal 40mi. if that

    ebikes and headwinds

    I believe it's the straight PW motor, an early motor from them. Current versions are up to 85NM of torque

    ebikes and headwinds

    I'm losing my kenda knobbies for schwalbe moto x street tires. Not enough off road to justify knobbies although the noise doesn't bother me

    ebikes and headwinds

    They do but the difference is 12 mph all day long instead of 6mph into the wind. I need earplugs just for wind noise now
