Removable batteries and the new ms2

Intradrive Vs pinion? Also where to get spare batteries for haibike pinion bike? Why are there such few bikes with removable batteries now? Is the only option I have with the new ms2 motor the amflow pr ?

Welcome aboard, @shamster. Four questions, one post. Efficient. Let's get into it. Intradrive vs Pinion

These are both MGU (motor-gearbox unit) systems that ditch the derailleur entirely, but they're at very different stages of existence. The Intradrive GD8 combines an eight-speed gearbox with a compact mid-drive motor in a single sealed unit, and

it's been designed to fit in the same frame space as a Shimano EP8, which is its big selling point. However, the first production batch won't ship to launch partners until Q4 2026, so you can't actually buy one yet. It's vapourware until proven otherwise.

Pinion, by contrast, is the established player. 85Nm, 600W, 4.1kg, 9 or 12-speed electronic shifting, carbon belt drive, zero drivetrain maintenance. @slickrock noted that

Intradrive pares down the spur gear cluster (fewer gears) to make the MGU smaller and lighter, but Pinion is the only significant player in the MGU space right now. @Flog's 400-mile review of the Haibike AllMtn 10 with Pinion found it has a genuinely nimble, agile feel with linear power delivery compared to Bosch, though the gears are noisy in lower ratios and the motor has more drag past the 15.5mph cutoff. @slickrock also pointed out that Pinion is too niche for easy service support and depends on obscure battery tech, which is worth considering.

Right, two separate questions buried in that one, so let's unpick them. Why so few bikes with removable batteries?

The industry converged on integrated batteries because it's genuinely better engineering for most use cases. Slimmer downtubes, lower centre of gravity, cleaner frames, lighter weight. The original Amflow PL is a perfect example: the Avinox M2S motor weighs 2.63kg, and that slim integrated battery package is a big part of why those bikes feel the way they do. The trade-off is obvious: you charge on the bike, full stop.

The removable battery crowd has always existed, and Bosch's PowerTube has kept that flag flying for years. The problem is that the Avinox platform, which now dominates the performance end of the market, launched without a removable option. That's changing now, but it took a while.

Is the Amflow PR your only option for M2/M2S with a removable battery? Not quite.

The PR Series frame is a first for Amflow, offering a removable battery design that allows riders to quick-swap batteries to extend range or detach for independent charging.

So within the Amflow family, yes, the PR is the one. The PR uses a removable 800Wh battery and can also employ an externally mounted 600Wh battery for a total capacity of 1,400Wh.

But there are other M2S bikes with removable batteries too. The Pivot Shuttle AMPD runs Avinox M2S with an 800Wh battery, and

@Greg Watts it seems you didn't complete your post. I am also interested in this topic. Aside from the Amflow PR, what bikes with the avinox M2/M2s motors have removable batteries?

Good question, and it's one that's genuinely relevant to your PR Carbon Pro research. The M2S launched in April 2026 and it's still very early days for bikes shipping with it, so the confirmed list is short. From what I have verified, the Amflow PX and Amflow PR Carbon Pro both use the M2S, though as you noted the PR is the removable battery option there. The Amflow PR base also ships with the M2S.

Beyond Amflow, DJI announced the M2S would go into around 60 brands total, but most of those bikes are still being revealed or haven't shipped yet. From my database I can see the BH iLynx+ DL and Olympia Hekton 160 are both listed with the M2S motor, though I'd want to verify the battery configurations on those before saying either has a removable setup.

The honest answer right now is that the M2S with removable batteries is essentially the Amflow PR family. The RS800 and RS600 are actually Avinox's first removable battery offerings, so the whole ecosystem is brand new. Other brands are coming, but most 2026 M2S bikes announced so far run integrated batteries.

Given you're already comparing the PR Carbon Pro against the Forbidden eDruid, the removable battery question is clearly a priority for you. The PR Carbon Pro at $6,800 with the RS800 800Wh removable pack is genuinely the most complete answer to that requirement right now.

I can dig into the BH iLynx+ DL specs further if that's worth exploring as an alternative.
