I have the Ultra eagle and I could have sworn on the Biktrix website they gave the option to purchase a 29" wheelset during checkout but I don't see it anymore. Does anybody know if I can put 29" wheels on this? And if Biktrix discontinued them which ones should I get? What would be the...

Don't get me wrong this is absolutely true. Whenever I'm in the upper 20s I feel like it's perfect I'm totally happy with that speed. That's why I still have my rear hub with 750w motor (juiced Ripcurrent S). It does feel sketchy going upper 30s but not going to lie it's still a blast going...

I updated my wheel size to 28 and I hit 43 mph going DOWNHILL level 9 max assist and holding the throttle and pedaling hard. I hit 38 mph on flat. I will be getting a go pro soon and try to record.

Do you mean to measure it like this? From the bottom of the tire to the top? It appears to be 28. So is this what I should update my wheel size to in the display?

Appreciate the offer but I need a 52v and the issue is due to the frame it's not able to fit their 21ah battery the highest is 17.5 and the owner said the mount may still need to be moved it will still be a tight fit

Do you have the Ripcurrent? My fat tire bike which is the 750w is the one that shows 30-32 mph on flat and there's a really steep hill here if I hit it at full speed it has shown 42 mph but my record was down even steeper hill and only once ever I saw it hit 47 mph but who knows if it's accurate.

I'm not on fat tires. I'm on 2.8" maxxis minion

This is Colorado I'm up on the mountain there's a lot of very steep hills here. What do you use to guage your speed?

Whats an accurate way to check my speed? Because if that's the case then the bafang speedometer is full of s*it. How would the back wheel be in the air? Are all bafang speedometer crap? Because on my rear hub with the 750w bafang motor on that display it shows 42 mph when I hit a particular...

Seems correct to me I have 27.5 tires

I bought the ultra eagle and got the stock 14.5ah battery and now I'm wondering if I should have gone with the 17.5ah. I wasn't sure if the 3ah difference would be worth the price difference so I didn't get it. I have a rear hub bike as well with a 52v 19.2ah and I can definately go further and...

Interesting, didn't know that.

I have the Ripcurrent S and thats the bike that I'm referring to which is more comfortable to pedal at higher speeds when I'm tired. It might just be rear hub vs mid drive then what I am noticing. On my 1500w mid drive I feel like I'm going slower and notice more loss of power/speed when I'm...

Theres still room for a 14% increase in my top speed which I'm going to do later just for the hell of it. I have a 50t chainring installed now and I'm going to upgrade it to 52t once the one I have now wears out. I will also need to change my rear cassette from 11-50t to a 10-42t.

Absolutely not!! You mean if the bike was on my stand with the wheel in the air and I hit the throttle? No I have not done that. This is from riding. I couldve hit a steep hill that I don't remember that got me to that speed. There's a lot of steep hills in Colorado. I'm definitely a speed demon...

Appreciate all the feedback!!!!

Though I will say that there was a learning curve as far as the settings and getting it tuned to my liking but not everybody has the same riding style. It's still supposed to be a mountain bike and not a high speed racer but everybody is different so learning the programming is really important...

😂😂😂 The crazy part is I had no idea I have gone that fast! I just noticed it last night and saw that one thread about it being difficult to achieve top speed! This is the ultra eagle. I also haven't hit any crazy downhills around here. If I did it would go over 50 for sure! But that's a bit too...

Awesome so with the setup I have now I just need to change the cassette to CS-XG-1175-A1 and to 52t chainring and that's it? I won't need to change my shifter or derailer or anything else? I don't use my lowest gear as it is infact it's been dangerous. I am more cautious about not going too...

This is my cassette: SRAM PG-1130 11-50T Is that what you meant? Do I need to go lower on the 11-50t number? Like an 11-46t? Or 11-42t? Right now I have so much torque that I only use the top 4 or so gears.
