Welcome to the forum,
@Newrider123. Four bikes shortlisted for your first eMTB - not bad for a newbie. Let's sort through this properly.
The headline problem with your question: the Trek Rail 5 and the Amflow PR are not really the same class of bike at all. You're comparing a £3,825 alloy workhorse to a £3,999 carbon rocket that doesn't actually exist in your hands yet. So let me break each one down.
Trek Rail+ 5 Gen 5 (2026)
The Rail+ 5 Gen 5 retails at around
£3,825 from most UK dealers. Across the entire 2026 Rail+ range, all models get the latest Bosch Gen 5 motor and the new 800Wh PowerTube battery, which is fully removable via Trek's RIB 2.0 system.
160mm of front and rear travel make it super capable in the rough and rowdy, and adjustable geometry lets you customise it for how and where you ride.
The Bosch CX Gen 5 motor is, frankly, the most
sensible motor on the market for a first-time eMTB buyer. Best dealer network in Europe, cadence-independent power delivery (flat from 50 - 100+ rpm), OTA-updatable, and it's been stress-tested by approximately one million German engineers. When things go wrong - and eventually they do - you can get it fixed.
Suspension is a RockShox Psylo Gold RC fork and Deluxe Select+ RT rear shock. Drivetrain is Shimano Deore 12-speed with Shimano MT4100 4-piston brakes. That's honest trail-level kit. Not fancy, but entirely serviceable and easy to upgrade over time.
As community member
@Stihldog put it: if he could only have one eMTB,
"it would be the Trek Rail 5. A change of tires and some upgrades could easily be done over time." That's from someone who owns both the Powerfly and the Rail 9.7 - so they've got the full picture.
Amflow PR Carbon (2026)
Now here's where it gets interesting - and slightly maddening. The Amflow PR Carbon is a full-power eMTB built around a lightweight full-carbon frame with the Avinox M2 drive system. At
£3,999 it represents the entry point to the PR Carbon range - and it is a genuinely capable trail and enduro-oriented eMTB.
The Avinox M2 delivers up to 125Nm of peak torque and works seamlessly with the SRAM S1000 Eagle Transmission electronic drivetrain via Amflow's SmoothShift function.
Head tube angle (five positions spanning ±1°), bottom bracket height (two positions) and chainstay length (440 - 452mm) can all be independently adjusted, giving up to 40 theoretical geometry configurations.
The Avinox OLED Control Display handles ride data, motor modes, offline navigation (GPX/FIT/TCX route import), Apple Find My location tracking, and Bluetooth connectivity.
The Avinox M2 motor is measured at around 1,100W peak - genuinely punchy. It's strongest above 80rpm (rewards spinning rather than grinding), so it suits riders who develop a proper pedalling technique. For a beginner, Bosch's cadence-independence is arguably more forgiving to learn on.
The catch - and it's a big one: This is "the most in-demand bike we've ever known." As of May, new orders are expected to be delivered
in late 2026.
So you're not waiting weeks. You're waiting
months, possibly into next year, for an unknown delivery slot, on a product from a brand that is still relatively new to UK dealer support infrastructure.
Quick comparison:
| Spec | Trek Rail+ 5 Gen 5 | Amflow PR Carbon |
| Price | ~£3,825 | ~£3,999 |
| Frame | Aluminium | Full carbon (~2.9kg) |
| Motor | Bosch CX Gen 5 | Avinox M2 (125Nm peak) |
| Battery | 800Wh removable | 800Wh removable (RS800) |
| Travel | 160/160mm | 160/150mm |
| Geo adjust | Flip chip | 40 configurations |
| Availability |  Now |  Late 2026 (estimated) |
| Dealer support | Excellent (Trek network) | Growing |
My verdict: The Amflow PR Carbon is the more exciting bike on paper. Carbon frame, more motor grunt, 40 geometry positions, electronic shifting as standard - at £3,999 it's slightly absurd value if you can actually
get one.
But. As a
first-time eMTB buyer, I'd lean towards the Rail 5 for these reasons: •
It exists, in your hands, now. You can ride it this week.
• Bosch's CX motor is the most forgiving motor to learn eMTB technique on. • Trek's UK dealer network means warranty and service are genuinely accessible.
• It's robust aluminium - less heartache if you're still learning where not to put a bike.
If you're comfortable waiting until winter and are willing to gamble on delivery timelines, the PR Carbon is tempting. But a bike you're actually riding is worth infinitely more than a better bike that's perpetually "coming soon."
What's your height/riding style? That'll help me check sizing on both, and also weigh in on the Whyte Kado and Orbea Wild you mentioned - those are worth discussing too.
