    I'd say until it becomes an issue with weeping oil or the suspension isn't performing well anymore. which is the same thing due to oil loss. The life can easily be extended by popping off the dust seals from the stanchions and cleaning them. Otherwise I reckon a safe bet is 6 to 10,000 km (3,730-6,200miles) or Every 1-2years depending on the amount of offroading.

    i charged it about a month ago after that video. It was pretty quick to charge and I haven't had to charge it since. I reckon the battery lasts longer because the horn automatically goes into standby after 40minutes. movement causes it to wake.

  • @jonoeuc
    @jonoeuc6 күн бұрын

    yeah I couldn't enjoy the street tyre at all. Yes I really like the shinko however it is a bit more difficult to learn on. due to the narrow centre tread which has less low speed stability. If you can ride a bit already then you should be good to go with the 241! The K262 will be fine too, it just struggles at faster cornering as mentioned in the video. More ride time helps with wobbles although the lynx is less stable at speed compared to say the sherman s. If all of that still isn't working out then i'd look at the pedal lowering kit. hope that helps, cheers jono

    Hi Jon, I rode down to 1% then turned on Lo Batt Mode. my question is at what voltage will Low Batt mode allow you to go to ? you said you stopped at 74v. thats 3.08v/cell. Im just trying to estimate how far "reserve" i will have in emergency. Also SHerman S states a battery capacity of 3.6kwh. I recharged from 1% today 77V up to 100.8v and it measured 3221Wh went back in ? If I had ridden some more in LO Batt Mode would this Wh number be closer to 3600Wh ? My Sherman has 9600km all up and going strong. Regards Andrew Muller in Perth.

  • @jonoeuc
    @jonoeuc4 күн бұрын

    The Lynx low battery mode goes to 2.9V or -25% of 0% charge. so 2.9V x 24series in the sherman s gives you 69.6V complete discharge on low battery mode. The manufacturer battery capacities are always wrong and overstated. the sherman s actual capacity is 3,335Wh based on 2A from my mates charts. So your battery capacity is in excellent condition. Nice distance and good to hear from an aussie cheers jono

    Awesome detailed review. Thank you so much. I can confirm your experience with off road vs street tire. I put a Heindenau K66 on my Master thinking it would improve high speed stability. The exact opposite was true. Really prone to wobbles and train tracking. Really scary above 60km/h. So strange as it was great at low speed as you found with the Michelin PS2. The only reason it seems to go for a street tire is if you need to corner super fast and need the EUC to stay a bit more upright. I actually find the CST-186 really good on my S18 but not so great on my Master. I think this might be because the rim is narrower on the S18 and the CST 186 is designed for a narrower rim. How wide is the rim on the Lynx?

  • @jonoeuc
    @jonoeuc4 күн бұрын

    good to know re K66. I was guessing it would behave like a linear, round street tyre. The CST186 has been getting some dislike from what i've seen so it just goes to show it all depends on the euc and rider. here is the lynx rim i.imgur.com/51YdqwI.jpeg

  • @eyeinthesky3013
    @eyeinthesky30133 күн бұрын

    The cst-186 only started getting bad reviews after it was installed as stock on the Master which was when the rim was widened. I've fitted a older narrower rim from a c38 begode exn onto my Master with the CST 186. Hard to say definitively but it seems to have improved cornering predicablity but made it more bouncy. The problem i'm trying to solve is turning very tight turns >90° off road. Just can't get the wheel to yaw round quickly. I have also fitted a CST 803 to see if it could improve matters. It is definitely worse and I've now refitted the K66 on the narrower rim. I expect horrible instability at speed on the road but hopefully it will solve the low speed off road tight turns. Unfortunately the 14 inch rim is not that common so tire choice is quite limited.

  • @guru_stu
    @guru_stu4 күн бұрын

    @@jonoeuc The formula is as follows for forward riding. If you are turning right you will want to balance pressure between inside heel and outside toe. If you are decelerating or accelerating backward and turning you will want the opposite...pressure on inside toe and outside heel. In euc's there is carving and there is slicing. Carving is like chooch rides ...almost always holding a slight turning. Slicing is when we find a neutrality in our riding and we can place our wheel on the road exactly where we wish to go....as precisely as pebbles on the taramak, being able to choose when riding on the paint lines: center, left or right as we choose. When we slice, the introduction begins with the movement at the ankles between the feet and the rest of the body. This is done by with flexion and extension of the ankle. Very often here people describe on eucs that we push into the pedals to accelerate, and push into the heels to decelerate...and this in practise can form counter forces that do not let the wheel perform as easily as it should. Think of the most simple robot that could ride an euc.. Feet that stand on an euc that just has straight legs that are connected to a robot pelvis . When the pelvis of this robot go forward dorsal flexion in its feet occurs so that the angle between the legs of the robot and its feet become more acute (less than 90 degrees). This happens by the toes coming into the shins. To accelerate heels press into the pedals to initiate pelvis to go forward. To decelerate the toes press into the pedals to bring hips backward. If we feel high pressure points on any parts of the pedal, very likely there will be an opportunity for us to become more efficient with our technique. Acceleration is determined by the angle created between the unicycle cm, our center of mass, and the earth we ride on.

    Great Video Jono. Thank you. WATT-HOURS really don't mean much. It is AMP-HOURS that tell how far you can go on a charged battery. Somehow, we need to get wheel manufacturers to tell us the AMP-HOURS we are buying without the WATT-HOUR/VOLT camouflage disguising the really important info of "AMP-HOURS." I have a Patton and a Sherman-S. With the Patton, I full-charge, ride gentle for 4-to-5-miles, keep it under 33-mph and then I get a 40-mile ride before low battery beeps. With the Sherman-S, I full-charge, ride as fast as I want from the start, keep High-Speed-Mode "off" (so 42-mph), and get 57-to-60-miles before low battery beeps. ... The WATT-HOUR and VOLTS announced for each wheel do "not" tell you what you need to know about a wheel's range. ... It is AMP-HOURS that matter. All Wheels: WATT-HOURS divided by VOLTS equals AMP-HOURS. Patton: 2200-WATT-HOURS divided by 126-VOLTS equals 17.46-AMP-HOURS. Lynx: 2700-WATT-HOURS divided by 151-VOLTS equals 17.88-AMP-HOURS. Sherman-S: 3600-WATT-HOURS divided by 100-VOLTS equals 36-AMP-HOURS. The Sherman-S has double the AMP-HOURS of either the Patton or the Lynx. If you like to cruise for hours at a time, and I do, the Sherman-S is your wheel. If you don't ride too far and want quick responsive torque and have about $3000(US) then the Patton is a good choice. If you don't ride too far and want quick responsive torque and have about $4000(US) then the Lynx is a better choice. ... Everyone. Ride well. Good journeys to all. ... NOTE: I am a 90-kilo/200-pound rider.

    How are you liking your tire? And what will be your next tire? Thanks!

    Love it. two issues are that it's very pressure sensitive so I have to check at least once a week. Even 31psi from 29psi made a big difference to round it out and make it more linear. I've had some oh shit moments cornering as the tyre transitions between the center and next line of knobs! checkout the tire comparison video for more details.
