Hey there Neeko! Thanks for joining in here. Liking the Ultra motor but it does eat the wh's even with very active pedaling! Need to get to the programming software......
Show us pictures of where you ride your ebikes!

Thanks @JRA.
Whilst I'll gladly admit that I haven't studied how Luna have programmed the ultra motor on their Z1 Enduro, I'd recommend just decreasing the maximum current from the stock 30amps to perhaps 25-20. Yes, this will effectively mean that you won't achieve the peak output of 160nm of torque. But you'll quickly find that your range will increase. And even at 20amps with 120nm of torque, the motor is still fairly powerful.
Without studying the programming Luna have done, I'd be reluctant to advise any further. They 'may' have kept to the stock settings for the Ultra but knowing Luna, they've changed values in accordance with how they wanted the Z1 to perform.
If you do get the programming cable and download the programming tool, screenshot it so I know how Luna set up the motor. I can then explain what parameters can be changed to increase range.
Regardless of whether you keep me posted on the settings or not, always remember to take notes (or a screenshot) of their settings. If all goes bad, you can atleast revert it back to how Luna programmed the motor.

More like 3rd or 4th at this point? On the opposite side of the "hill" there are true old growth trees, mostly Sitka Spruce, and in fact the largest one in Oregon.
They are protected by a State Wildlife Area. One of my hobbies is searching out any old growth that are left. It is just good fortune that I ended up living about a mile and a half from a grove of them!

i normally ride in and around the san francisco bay area, but took a quick trip with friends to the oregon coast and did a couple rides. very different scenery, a beautiful coastline, LOTS of logging / logged forests, gentler hills, and about 10x as much water… on the ground and coming from the sky.

Winter time is trail work/development time here.
Old logging property has lots of potential for finding trails to rebirth from old skid roads from when the area was first logged. Basically just finding them and opening them up and riding them in!
New bike yielded some issues that need to be worked on during clean up on the already established tracks.....
Hmmm, do I cut down the bars or one of the trees?
Edit 12/22: The tree on the left lost and bars are still stock. I finished off that trail and am on to the next!

This is just one section of a cut that was done for an underground powerline that feeds some homes high on a ridge top where the ruts in the road keep the tourists at bay, along with a bunch of no trespassing signs.
One can only imagine how much that must have cost as it has to be over 5 miles long.

Del Valle? If it is, it’s been too long since I’ve been there. And I’ve never taken a bike ride over there…just a bit of fishing.

Yep, a Hydra.
Yes it is. And I too had never gone there with a bike. There are seemingly tons of trails to explore, I’ll be going back. This is time of year to go too it seems, green hills. Some great views.

Feel free.
I grew up in snow, VT., and lived for years in elevation snow country, CO., and don't miss it much living where I do now. Although the coast is forecast for snow tonight/tomorrow and up to 12"es possible. Even if it comes it won't last long but all freezing precautions are in place. Always interesting when it does happen here though and a good idea to just hunker down...

So out of curiosity, I decided to increase the travel on the Freedom (my 29er bafang Ultra emtb which I built a while back).
Originally, it had 140mm travel front and rear running on 27.5 wheels. I opted to run the Freedom as a 29er mid year and decided to play around with it more before committing to my new projects
Since that video, out back it has 150mm of rear wheel travel. Upfront, 180mm of travel.
At first, I did think it was overkill. But 'hand on heart', it actually works.
As I've long since suspected, the 'Chinese styled' emtb frames tend to work best when they are over-forked. Whilst at first, you may question whether the geometry would worsen. In real world applications through trail riding, the performance (both climbing, descending, flow etc), increases the performance in terms of handling and efficiency as the rider Is put in a better position.
This discovery will be useful for my new emtb frames which I'm slowly building.
But for now, hopefully everyone is having a good Christmas/new year/much deserved rest period

"As I've long since suspected, the 'Chinese styled' emtb frames tend to work best when they are over-forked."
Which in turn slackens the head angle slightly bringing that aspect more into line with modern geo angles. Slows steering a bit but the wider bars take up the slack there and adds stability when pointed downhill. If you could get Frey/DengFu and others to make the quantum leap into fully modern geo it would be great instead they seem to just want to chip away at it. Even pretty easy to do as bike companies that have figured it out regularly list their figures online....
Happy New Year to you Neeko and stay safe and ride sane.
