Speed up
Your synchro's are going bad, common problem with the ax5. The synchro gear will match the speed of the two gears so they meet smoothly, when these wear out you will get difficult shifting and some grinding.
If it is stuck in gear that typically means there is a synchro problem. The synchro ring is likely worn out and jams up, preventing shifting gears.
synchro second and third gear, not first gear
Downshifting refers to the process of shifting to a lower gear in a vehicle to decrease speed or increase torque. This is commonly done when slowing down, going uphill, or to better match engine speed with road speed.
It will not harm the transmission to skip a gear (any gear) while up shifting. You go into neutral during each shift, the transmission doesn't know which gear you came out of. The transmission only matches speed to the engine and to the wheels for the gear its in. Be careful during down shifting, you don't want to skip too far ahead and run the RPS's too high.
Not engaging clutch completely speed shifting ( badly ) Gear grinding Downshifting at high revs shifting without the clutch Anytime the gears are forced together or grind the ears on the syncro are worn down and wont fit together smoothly
The first cause of the jump out from one to other gear is the loose shifter fork, which connects the shifting linkage and gears of the transmission. The second cause is loose shifting linkage itself, which connects the gear shifting knob and shifting fork. The shifting linkage and shifting fork become loose due to the rapid changing of gears from one gear to other at high speed of vehicle. The third cause is the misalignment of shifting linkage to the shifting fork.
If you already know how to shift an unsynchronized transmission, I'm guessing you learned on a 10 speed. The difference is... eliminate the first and sixth gear from a ten speed, and you have your nine speed shift pattern (as well the base shift pattern for the 8LL, 13 speed, and 18 speed). Schools teach you to take it out of gear at 1500 RPMs and drop it into the next gear at 1000 when upshifting, and they teach you to take it out of gear either at 1000 RPMs, take the engine up to 1500 RPMs, then drop it into the next lower gear when downshifting. Shifting at 1500 bogs down the engine... I upshift at 1900.
Check your fluid level, the synchro's are not working, and it may be because theres no lube.
An automatic gear shifting bicycle offers the benefits of convenience and ease of use compared to a manual gear shifting bicycle. With automatic shifting, the bike adjusts gears automatically based on speed and terrain, allowing for a smoother and more efficient ride without the need for manual gear changes. This can result in a more enjoyable cycling experience for riders of all skill levels.
You may have shifted into reverse by accident, I've done it a few timesAnswerYou may also be having problems with the synchro rings that allow the gears to mesh without the grinding. 1st-2nd gear share a synchro and 3rd-4th gear share a synchro too. It sounds like the 3rd-4th gear synchro may be worn.
Your synchro is most likely going bad, the same one works for 1st and 2nd so 2nd should be giving you trouble too.
