InMotion V11

Recommended Posts

V11 tire pressure recommendation for 230 lb rider with gear maybe 240 lbs have this chart from ewheels but does not have 18”x3” listed.

My guess is around 44 psi.

44psi is far too much for my personal preference. I set the tire around 35psi and had a horrible time with turning and wobbles, but acceleration was improved. 

30-32psi works good for me. (250-275lbs)

On a different front, I tried lowering the pressure in the lower chamber from 170psi to 150psi. Not a fan, felt very sluggish. Slower rebound was good for curb drops though. 

Going back to 170psi. 

Need to get confirmation on max psi for top chambers. I am currently stopping at 50psi.

Will try 32 psi on tire. Try 170 bottom and 80-85 on the top chamber if too much try a little less. I am convinced that 50 psi on top chamber is not enough and will be too bouncy.

I am going with 160 bottom and 80 on the top and fine tune top chambers, lowering a little amount if needed.

What is the pressure limit for the upper chamber? I thought it maxed at 50psi...

50 psi was just a blanket recommendation from IM. Haven’t heard of a maximum. I have found 50% (45-55%) of the main chamber to be ideal. Lower than that and small bumps are harder and the suspension is bouncy, higher than that and the suspension travel gets shorter.

 My optimal is currently 165/85 for 108kg (~240lbs?) geared up.

Thank you Mrelwood!

Went adjust the upper chambers up to 90PSI and found that I have another flat tire, lol.

Applied more Slime and put a fresh valve core in. I have a replacement tube (but looking for a work around until the weekend). Seems to be holding pressure so far.

No pressure loss in my upper chambers after at least a week of riding 

Top chambers are easily accessible without removing the saddle(s) with the right pump (at least this morning it was, lol).

First crash tonight  - 

I was heading to hardware store after dark and had a slight mishap with concrete/gravel transfer. This was probably karma catching up to me concerning my torque comments, lol.

I hit a dirt embankment that connects to one of the sections of the path I was traveling on and everything went wrong. I did not have a phone on me at the time so I do not know my exact speed,  but I assume that I was accelerating from a lower speed as I had just crossed a busy intersection (10-15mph). As soon as I transferred from concrete to gravel the wheel washed out hard to the left which blew my left foot off of the pedal.

Needless to say this all happened very fast and by the time I realized that I was in trouble I was still cruising forward with left foot hanging off the side of my wheel. I jumped off using the foot that was still on the right pedal and was able to clear the wheel and run out the bail. 

First thing I checked post bail/crash - nobody saw the crash_CHECK

Second check - injuries_none, good leap, lol

3rd check - wheel_Wheel tipped over on right side in dirt and ended up further down the concrete. Upon initial inspection the unit was still powered on, but the pedals appeared to be in tiltback mode. I cycled the power and the pedals returned to default position. The upper portion of the right front end was well covered in dirt. I did have some scraping to the outer edge of the right pedal as well as the hanger. Very impressed with the durability. 

Root Cause (Assumed)

assume that when I transferred to the loose gravel the wheel lost traction for a moment. When I lost traction I also lost footing on the left pedal as the wheel turned with the unexpected pressure from a single foot (at moderate speed) and coupled with whatever my body was doing to stay upright/launch off. 

I went back and reviewed the tire tracks. There is a curve to the left right after hitting the dirt which adds up. Interestingly there was a good amount of straight tire mark post curve so I probably could have rode it out if both of my feet were on the pedals.

user error for sure, lol.

Good that you weren’t hurt! Gravel can be a ditch. My first EUC crash with (a little) bodily damage was a puddle of wet gravel on a small construction section of a dirt bicycle path. My 16S turned to the left in an instant, and my attempt to run it out didn’t pan out for more than a few steps.

Placed an order on my first 18” wheel in a few days...

Upon inspection this morning I found additional cosmetic damage to the panel that covers the wheel and the side of the light housing. Wheel is still running like a champ and I am quite impressed how well it took a crash at moderate speed.

I was leaving the market tonight and was approached by a gentleman and his two young daughters. One of the little ones questioned what I was riding to her father. The father's response made me think of Unventor's quest - "It is a one wheel car"

The "T-spinner" and large socket make removing/installing the suspension, pedals-hangers and components a breeze.

Concerning the bolts right above the pedals - a 4mm allen socket (by hand) tremendously speeds up removing/installing those bolts.

Was having fun cruising a path near my house and on my way back home I got a horrible bee sting to the throat (while at 20mph)... but I did not crash! Watch out for bees, lol.

Through my UNOFFICIAL testing I found that my V11 in "fancier" mode beats my MSP off of the line (considerably). 

I need to re-calibrate the pedals on the MSP to match the stance of the pedals on my V11 and test again.

This is why I like my TSG pass helmet as no beers or hornets can enter an air vent or open visual area as long I have the visor down. 

My neck/throat area is a difficult area in summertime though.

I would like to have a second full face helmet and throw away my half shell helmet... Thanks Unventor!

I ended up with a welt the size of a golf ball at the base of my neck. I lost my composure when I saw it, but my wife brought me back to Earth - 

N - Can you breathe?

P - yes, but it hurts and looks awful

N - You would have been dead by now if something was wrong, now go take out the trash...

Sounds like a smart wife 😁

Not sure why people are still saying that the V11 is not a performance wheel. Fancier mode addresses this notion very well.

I know that I spouted off and said and said that the V11 was quicker than the MSP the other day... well it is*, off of the line (acceleration). Not top speed. With very little effort (my pedals are set at -3).  

I previously questioned what more a F model could add, but this wheel would be even better at 100V... and slightly wider with way more batteries. Or more batteries in the form of a shell shaped like power pads.

*for me
