I had a similar frustrating experience with a Trek Rail 9.7- it was a creak only under load. After ruling out the motor, drivetrain forks, headset, and shocks ( I swapped parts from other bikes one by one) I was convinced a suspension bearing had failed. I pushed out all the bearing and found...

Looking for tires that will work well in both wet and dry conditions. Current set is Maxxis Assegai front and DHR II rear. What do you suggest? Thinking about keeping rear and putting a High Roller III up front or going to a magic mary and big betty combo

We’re building a community of e-MTB riders right here in Marin County, and we’d love for you to join us. Our focus is on scenic, approachable routes. Our Ride Schedule: Wednesday Lunch Rides: A quick, 1-hour mid-week recharge. Weekend Explorations: At least one longer ride to soak in the...

Right now, I’m running the High Roller 3 (Exo+) up front and a DHR 2 (DoubleDown) in the rear. For mixed winter conditions, it’s hitting the sweet spot. Why this works over the alternatives: The Shorty: I’ve benched it. Unless it’s a total mud bog, it feels way too squirmy and slow.. The Rear...

Agreed - Yeti 160 E handling once you get them up to speed is at another level. Agreed — the Shimano EP801 is an excellent motor. Ours have been completely trouble-free, and we’re careful not to blast water into them when cleaning. The power delivery feels natural, and noise levels are...

FWIW - Talked to Shimano - so for EP8 (not 801) if you are a larger rider (ie 200 lbs plus) going up a steep 20% slope you will likely maximize the 85 NM output in Trail mode with assist character set to 7 so switching to Boost mode with the assist 10 (default) makes no difference in perceived...

Going up a steep hill with the same cadence switching from Trail to Boost I feel nothing has changed on an EP 8 bike on a EP 801 bike(Trail to Boost) or Bosch CX bike (EMTB to Turbo) it is a significant difference. Also, for even steep climbs I rarely ever climb in the biggest cog in the rear...

Steve, I have 2 settings for Assist - Assist Character (AC) and Assist Start (AS) - AC is suppose to determine how much rider input is needed to ramp up the motor to full power and AS determines how much power you get when you first step on the pedals, the later controls wheels spin when...

EP 801 bikes can be tuned to have a way earlier assist ramp than an EP 8 bike and rival the output of a bosch CX bike. The EP801 is a totally different tuned motor than an EP 8. Assist Character is supposed to determine how much rider input effort is necessary to obtain full motor assist...

I have an EP8 bike with Trail set to assist 7 and max power at 85 nm and Boost set to assist 10 and max power at 85 nm. I feel no difference in assist going up steep climbs between Trail and Boost mode. I weigh 215 lbs so to get me up steep hills requires a lot of effort perhaps I am already...

A word of caution - stripping or overtorquing your motor mounts or any part of the crank spindle (integrated into the ebike motor for all mid mount motors) can result in having to send a motor or frame in for repair ($$$). To reduce the risk of your home repairs resulting in costly damage -...

We have one EP8 and one EP801 yeti and we have no rattle issues at all. The Shimano rattle and Bosch rattle have never been big issues on any of our bikes, some manufacturers implemented things better than others to reduce the motor noises. As far as low power TQ or Fazua bikes they are more...

245 lbs is fine for Yeti suspension range setup. Whether or not 630 watt battery is enough for you depends on where you ride, how far you ride, and how fit you are. You can always buy a spare battery to carry for big days, but if you have to use one everyday you probably need to go with the bike...

Frequent use of e-bikes, particularly when riding daily, often leads owners to invest in multiple bikes. This is largely due to the increased likelihood of mechanical issues and the challenge of sourcing specific parts, which can be difficult to find or order promptly. Maintaining an inventory...

Steve, Unfortunately, most folks are not as positive as you, if this was a post about product failure I am sure many more folks would have jumped in. Overall, I believe Shimano and Bosch make great products and so long as you don't submerge the motors in mud, put them underwater doing stream...

We have two 2019 Trek Rail 9.7's with Gen 4 motors - the first ride out 5 years ago we rode through a mud bog that submerged the motor for about 5 seconds. I remember rushing to the Trek store worried that we had ruined the bikes, they told us to try and avoid submerging the motor, but that...

I am the same height as you and test rode both medium and large - when you say it felt small - what are you referring to ? In the saddle or out of the saddle descending ? With proper saddle position and bar choice I can make my Medium Yeti's seated cockpit feel very close to my large Trek...

The Orbea is a well sorted bike, if you try to buy one instead of the YETI make sure you have a local shop that either stocks parts or can show you evidence they can get parts quickly ---- ebikes break way more often than analog bikes and have custom parts you cannot easily source from alternate...

Mountain Biking Context: E-Bike Experience with Trek and Yeti Background: With three decades of mountain biking experience, we've transitioned into the e-bike world through two notable models: Trek Rail 9.7 and Yeti 160E. Rather than selling our initial Trek bikes, we've kept them as versatile...
