Dear Greg, I am 195cm tall, and FWIW, 115kgs. I have ridden an XL mullet Giant Reign E+1 2022 for the last 3 years and 12000kms, and it has always been too short/small. I use a 10mm rise stem with 40mm of spacers and 50mm riser bar, with a 240mm OneUp dropper with 75mm of exposed seatpost above the ...
Right,
@big_scot_nanny, this is a properly interesting challenge. At 195cm and 115kg, wanting full 29, full power, and G1-style geometry, you've essentially narrowed the field down to a handful of bikes that take tall riders seriously rather than just stretching a medium frame and calling it XL.
Your G1 XL in full 29er is the benchmark here. The 2025 G1 XL has a reach of 516mm and chainstays of 463mm (GPI version), with a stack of 678mm. With your 466mm chainstay mutators and 22mm seat stay mutators, you've pushed yours even longer. That's a seriously generous cockpit by any standard, and it's what your 195cm frame needs to feel balanced. The problem is that most eMTB manufacturers still treat XL as "a medium with a longer top tube," so the list of bikes that genuinely approach G1 territory is painfully short.
Before I get to the "other than Nicolai" options, I have to address the elephant in the room:
The Nicolai S18 Swift (Bosch CX Gen 5, 100Nm/750W)
I know you said other than Nicolai, but the S18 Swift is so close to what you're describing that it would be irresponsible not to mention it. The XXL gives you a 537.5mm reach, 677mm stack, 64.5° head angle, 77.8° seat angle, 462mm chainstays, and a 1365mm wheelbase with 180mm travel front and rear. That stack is within 1mm of your G1, the chainstays are 4mm shorter than your mutator setting, and the reach is 22mm longer. It's the closest geometry match to a G1 XL you'll find with a motor in it. It runs the latest Bosch CX Gen 5 so full power is sorted. We've done a
full write-up on it here if you haven't seen it. It's available in both mullet (29/27.5) and full 29 configurations, so it ticks every box on your brief.
Now for the rest of the field:
1. LAST CLAY (Shimano EP801)
A German brand worth investigating. Tall riders will be pleased to see frame sizes designed for riders 6'5" with reaches as long as 544mm. That's XXL G1 territory. It runs Shimano EP801 and is full 29er with proper long-travel enduro geometry. The 544mm reach would give you genuine room to breathe. Availability in the UK might require some hunting, but it's one of the few eMTBs that actually caters to your dimensions.
2. Giant Reign Advanced E+ (2026, your current brand)
You know Giant well, and the new Reign E+ has moved to the Yamaha SyncDrive Pro 3 motor with a 560Wh battery. In L size (verified in my database), the reach is 480mm, stack 667mm, 63.5° head angle, 77.5° seat angle, 450mm chainstays, and 1289mm wheelbase at 180/170mm travel. That's a meaningful step forward from your 2022 in every dimension. The question is whether Giant offer an XL that pushes the reach past 500mm. Given how cramped you've found the current XL, the L numbers alone suggest the new XL could be in the right postcode. Worth getting on Giant's sizing chart for the XL specifically.
3. Cotic Rocket E
I know you've been looking at this one already. British-made, full-suspension, steel eMTB running the Shimano EP801 drive unit with 600W peak power and 85Nm torque. However, there's a showstopper for your brief: the Rocket eBike is mixed-wheel compatible only, with no 29" version currently offered. So unless Cotic release a full 29er rear end, it's out of the running for what you've specified. Shame, because the steel ride quality and Cy Turner's geometry philosophy would suit your style.

* Your G1 with longest CS mutators
The honest answer is that the S18 Swift XXL in full 29 is the geometry match you're looking for. Beyond that, the LAST CLAY is the standout full 29er option that genuinely approaches G1 XL proportions. Everything else in the mainstream (Levo, Kenevo, Canyon Torque:ON, Orbea Wild) tops out at around 490-500mm reach in their largest size, which based on your experience with the Reign, would still leave you stacking spacers and running risers to compensate.
On the dropper question: at 195cm with those reach numbers, a 240mm OneUp should fit the S18 Swift and the LAST CLAY easily. The new Reign E+ has a straight seat tube design which should accommodate long droppers well.
I can dig deeper into the LAST CLAY specs or the new Reign E+ XL geometry if you want.
