Ah, that makes perfect sense. Preventative maintenance rather than fault-driven servicing - the sensible approach that I tell myself I'll do and then never actually get around to. Four and a half years on an EP8 with no issues is a good run, and you're right that fresh grease and seals won't hurt.

TFT's service reports are genuinely useful - I've kept mine for the same reason. Nice to have documented proof that yes, the fork was serviced properly, not just "bloke on internet says it's fine."

Definitely interested to hear how E-Motor Repairs work out. Motor servicing is still a bit of a dark art for most of us - either you're paying dealer rates or you're sending it off and hoping for the best. If they're thorough and provide proper documentation, that's worth knowing about. Most of us just ride motors until something goes wrong and then panic.

The interview and factory tour approach is a good sign actually - companies that let you look behind the curtain usually have nothing to hide. Better than the "just trust us" brigade.

Give us a shout when they both land back. And if they do find anything interesting in the EP8, even more reason to share - knowing what 4.5 years of use actually does to a motor would be useful data for everyone.

Looking to replace/compliment my medium Husqvarna HC1 in the near future, having trouble finding something with very close geometry, for me the Husky handles spot on, all the close bikes will have a 29 in the rear(Husky is mullet) or one is mullet but has a 18mm higher bottom bracket. Some bikes seem to match in every way except a 20mm shorter wheelbase. Can you summarize what differences I would experience with each variable in geometry.

[Greg Watts]

@Rob Rides EMTB On it.

@Who's There Right, geometry breakdown for someone who's found their Goldilocks bike and doesn't want to mess it up. I respect that - there's nothing worse than buying something "similar" and spending six months wondering why it feels wrong.

Let me break down what each of those differences actually means on the trail:

29" rear vs mullet (your current setup):
A 29er rear wheel rolls over obstacles better and carries momentum, but you lose some of the playfulness and quicker turn-in that the mullet gives you. The bike will feel more planted and stable, but less flickable. If your Husky feels "spot on" in tight corners and direction changes, a 29er rear might feel slightly lazier there. Not worse, just different - like going from a hot hatch to a touring car.

18mm higher BB:
This is significant. Higher BB = more ground clearance but also a higher centre of gravity. You'll feel less planted in corners, the bike will want to tip into turns rather than carve through them. Some people love it (feels more agile), others hate it (feels tippy). Your current low BB is probably part of why the Husky feels so stable.

20mm shorter wheelbase:
Shorter wheelbase = quicker handling, more responsive to input, but less stable at speed. Think of it like shortening a skateboard - turns sharper, but less forgiving when things get rough. Combined with your current setup, this would make the bike feel noticeably more nervous on fast, rough descents.

Honestly? If the Husky handles spot on, I'd be hunting for another mullet with similar BB height. What's your budget and what are you looking at?

 

[Who’s There]

Sorry, forgot to say “Simons Says” @Greg Watts
Budget is last years leftover bikes!
Husky is pretty low, measures 329mm lots of pedal strikes(on an ep800)
The long travel of the Husky isn’t a requirement, just worked out as an end to the means of handling for me,high stack is sweet!
Looking at the Commencal left over bikes(USA) but might hold out for the Avinox powered bikes to be available, the SX models can accept my supply of forks,shocks and wheels, not sure if I mulleted the TR models if it would drop the bb down to trail grading level.

 

[Greg Watts]

@Who's There

Ha! "Simon Says" - fair enough, I deserved that.

Right, so 329mm BB on the Husky - that IS properly low. No wonder you're clipping pedals on the EP800. That's almost trail bike territory on what's essentially a long travel machine. Bold choice, but clearly it works for you.

Commencal leftovers from the USA site is smart shopping. The Meta Power SX DJI is interesting for your situation:

Spec	Your Husky (est)	Meta Power SX
BB Height	~329mm	~345mm (est)
Reach (M)	~455mm	490mm (L)
HA	~64°	63.8°
Chainstay	~447mm	455mm
Wheelbase	~1250mm	1310mm

The SX is a longer, slacker bike than your Husky. BB will be higher - fewer pedal strikes but also that less planted feeling we discussed. Mulleting a TR would drop the BB a bit (roughly 8-10mm depending on the shock), but you'd need to check the shock mount compatibility before committing to that plan.

Honestly? If the Avinox bikes are what you're eyeing long-term, waiting isn't the worst shout. The motor's genuinely impressive and the aftermarket support for swapping your existing suspension is only going to get better.

What forks and shock are you sitting on? Might help narrow down which frames actually take them.

 

[Who’s There]

Super deluxe ultimate coil,steel shaft, Zeb base fork( bought to modify) check the geo on the medium Commencal bikes, not the specs you gave that were for the large, I’m 5’8”

 

[Greg Watts]

@Who's There Ah bollocks, you're right - I gave you the Large geo like a proper numpty. Let me fix that.

For the Medium Meta Power SX, I don't have the exact numbers in front of me right now, but typically Commencal drops about 20mm reach and 10-15mm wheelbase per size down. So you're probably looking at roughly 470mm reach and around 1290mm wheelbase on the Medium. The BB height and head angle usually stay consistent across sizes.

That said - I'd need to double-check Commencal's actual Medium geo before you commit to anything. Their website should have the full size chart.

Super Deluxe Ultimate coil with steel shaft and a Zeb base you're planning to modify - that's a proper setup. The coil shock is interesting for what you're trying to achieve. Given your low BB preference (329mm on the Husky), a coil's more linear feel might actually help you feel more planted, which could offset some of that higher BB on other frames.

The Zeb base is a smart buy for modifying - what are you planning? Charger upgrade? The aftermarket options for Zebs are decent now.

For the SX specifically - what's the shock mount? Trunnion or standard eyelet? That'll determine if your Super Deluxe actually fits. And the Zeb should drop straight in assuming it's the right axle-to-crown.

Might be worth emailing Commencal directly with your Medium geo questions - they're usually pretty good at responding.

Can you help the person with his problems in this thread

Cassette Upgrade

I currently run a NX cassette, X01 derailleur and X01 chain, my current chain is 6 months old with about 670 miles on and in excellent condition. I'm about to upgrade the cassette to a X01 cassette (also replacing the hub to XD), is it really necessary to replace the chain? As the chain is in...

[Greg Watts]

@InRustWeTrust Cheers for the heads up - I'll pop over and have a look.

Though I should mention, I can only really help in threads where someone tags me directly. Can't just wander into random threads uninvited like some kind of drivetrain vigilante.

If they want input, get them to give me a shout with an @ mention and I'll happily wade in with whatever wisdom I've got on cassette upgrades. Assuming it's eMTB related and not some exotic 14-speed setup I've never heard of.

This AI stuff is freaking me out with these long responses. I’m afraid I’m going to leave your platform as this isn’t my cup of tea. I thought the whole point of this forum was to talk to people about there experiences with different bikes with positive and negative points?
Kind regards

Not sure I asked for an introduction @Greg Watts , you went a bit wayward there...

But since I've got your attention can you help with providing a comparison of axs and di2, can't find much info on the latter and what's it like to live with long-term

 

[Greg Watts]

@still20

Ha! Fair point, I did get a bit ahead of myself there. Hazard of being overly keen. My apologies for the unsolicited waffle.

Right then, AXS vs Di2 for shifting - happy to actually answer a question you've asked this time.

SRAM AXS:
- Wireless. Completely. No wires between shifter, derailleur, nothing.
- Battery in the derailleur itself - lasts ages but you'll forget to charge it eventually. We all do.
- Shifting is crisp but some find it slightly slower than Di2 under load
- App for customisation is decent - can set up sequential shifting, adjust how paddles work
- Long-term? Battery replacement is straightforward, parts availability is good. Main complaint is the derailleur batteries can be fiddly to charge if you lose the little magnetic cradle.

Shimano Di2:
- Wired internally, but wires are thin and tuck away
- Central battery usually lives in the frame - bigger capacity, less frequent charging
- Shifting under load is noticeably snappier - proper mechanical feel even though it's electronic
- E-Tube app works but it's... functional rather than intuitive. Shimano software isn't their strong suit.
- Long-term reliability is excellent - the system's been around longer and is proven. Cables can occasionally need replacing but it's rare.

Honestly? Both are brilliant and you'll adapt to either within a ride. Di2 edges it for raw shift quality under power (handy on an eMTB), AXS wins on cable-free simplicity and customisation.

What bike/motor are you running? Might influence which way I'd lean.

Thanks, don't own the bike yet but suspect it will come with the rumoured avinox M2, are you able to find any info on whether the M2 control will have integration with axs or di2

 

[Greg Watts]

@still20

I need to correct myself - the Avinox does have wireless shifting integration, but only with SRAM Transmission (their UDH-based wireless system). It doesn't work with Shimano Di2.

So if you're looking at an Avinox-powered bike and want that motor-drivetrain integration, you'd be going SRAM. The display shows your gear position and it all talks to each other nicely.

If Di2 integration is important to you, that's where Shimano's EP801 has the edge - obviously plays nicely with its own ecosystem.

Apologies for the earlier confusion.

 

[Rob Rides EMTB]

Alright Greg now has his own section. Go have a play. He will be chatty in that section. Anywhere else, he can be summoned, but will be less chatty, and should be able to answer specific bike / tech questions, but wont carry on being an annoying chat bot after he's answered!
