Recommended tire pressure for Amflow Carbon Pro?

[EdK]

Hi, have 162 miles on my Amflow, Absolutely awesome bike! What air pressure do you recommend for front and back, moderate terrain?

I'm on a Amflow Carbon Pro.

Hi, have 162 miles on my Amflow, Absolutely awesome bike! What air pressure do you recommend for front and back, moderate terrain? I'm on a Amflow Carbon Pro.

Welcome to the Amflow club, @EdK. 162 miles in and still grinning is a good sign.

Tyre pressure is one of those things that depends heavily on your weight, the tyres you're running, and what "moderate terrain" means to you, but I can give you solid starting points based on what the community runs on similar bikes.

For a typical rider in the 80-90kg range (kitted up), you're looking at roughly 20-22 psi front and 22-25 psi rear as a sensible starting zone for moderate trail riding. The front always wants to be a touch lower than the rear because more of your weight (and the motor's weight) sits over the back end, and you want that front tyre to deform slightly into the terrain for grip. If you're lighter, drop a couple of psi; heavier, add a couple.

A few things worth knowing: the Amflow Carbon Pro is a capable machine with 160mm front and 150mm rear travel, so the tyres are genuinely your first line of suspension. Too high and you'll bounce off roots and rocks rather than tracking over them. Too low and you risk rim strikes and a vague, squirming feel in corners. The sweet spot is where the tyre deforms enough to grip but doesn't fold under cornering load. If you haven't already, a calibrated digital gauge (the Topeak SmartGauge D2 is popular) makes a huge difference compared to guessing with a track pump dial.

For spring conditions specifically, trails are drying out but still soft in patches, so err slightly towards the lower end of those ranges for better grip on the damp stuff. You can always add a psi or two as things firm up into summer.

If you let me know your riding weight and what tyres you've got on there, I can narrow it down further. I've also got community data on specific tyre and insert combinations if you want to get properly dialled in.

Question, how does the Forbidden Druid DJi compare with Amflow. Looking for second bike (small) S2?

Question, how does the Forbidden Druid DJi compare with Amflow. Looking for second bike (small) S2?

Right, two things to address here, @EdK. First, your weight: at 170 lbs (about 77kg), you're a touch lighter than the range I gave earlier. I'd nudge those pressures down to around 18-20 psi front and 20-23 psi rear as your starting window. That'll let the tyres conform nicely to roots and rocks without squirming around on you. With spring trails still holding some moisture in places, sitting at the lower end of those ranges will serve you well for now.

Now, the Forbidden Druid comparison. I should clarify first: are you looking at the Druid CorE (the full-power DJI Avinox eMTB) or the Druid LitE (the lighter, lower-powered version)? You mentioned "DJi" so I'll assume you mean the CorE. These are genuinely different beasts despite sharing the same motor platform. The Amflow is a 150mm travel trail bike, nimble, light for a full-power eMTB, and brilliant at climbing. @David1960 summed it up well: the Amflow is brilliant at ascending and lightweight, though not as steady on descents as a true enduro bike. The Forbidden Druid CorE, by contrast, is a burlier machine with a high-pivot suspension design that carries speed through rough terrain impressively. @jbrown15 describes the eDruid as a burly enduro build, way beefier than the Amflow which is more of a trail bike.

The review comparisons bear this out. @Nomadic Dad referenced an ebike-mtb test where the Amflow ranked as the top DJI climber, while the Druid CorE was rated the best all-rounder among the DJI bikes tested. So if you want a second bike that complements the Amflow rather than duplicates it, the Druid CorE makes a lot of sense: keep the Amflow for big days out and flowing trails, use the Druid for chunkier, more gravity-oriented riding.

Additionally, now that I've got the full geometry numbers, let me put this all together properly for you, @EdK.

First, your tyre pressures. At 170 lbs (77kg), you're lighter than the range I initially quoted, so I'd drop those numbers a touch: aim for 18-20 psi front and 20-23 psi rear as your starting point. With spring trails still a bit damp, lean towards the lower end for grip.

Now, the Druid CorE versus your Amflow. At 5'6" you'd be looking at the Forbidden S1 or possibly S2, and on the Amflow you'd be in the M (the smallest size available). Here's the thing: one setback with the Amflow is the truncated size range, where the shortest option is the medium with a reach of 452mm, which will leave smaller riders stretched out. The Forbidden, by contrast, starts at S1 with a reach of 430mm and stack of 628mm, then S2 at 447mm reach and 649mm stack. That proportional sizing is a genuine advantage for someone your height.

Here's a side-by-side in S2 (the size Forbidden recommends for 5'6"-5'10") versus the Amflow M:

Spec	Forbidden Druid CorE S2	Amflow PL Carbon M
Reach	447mm	452mm
Stack	649mm	618mm
Head Angle	64.0°	64.5°
Seat Angle	76.75°	77.0°
Chainstay	442mm	445mm
Wheelbase	~1230mm	~1230mm
Travel (F/R)	160/150mm	160/150mm
Wheels	29/27.5 (MX)	29/29 (MX optional)
Motor	DJI Avinox M1	DJI Avinox M1
Battery	800Wh	800Wh
Weight	~22.6kg	~21.1kg (M)
Dropper	180mm (S2)	Variable

The big difference that jumps out is stack height. The Druid CorE S2 has a stack of 649mm

versus the Amflow M's 618mm. That's a 31mm difference, which is massive. Forbidden deliberately increased stack to lift the rider's centre of gravity up and back on descents, creating a standing position more akin to a downhill rig. The Amflow's lower front end is something multiple reviewers flagged: the low front end is a clear drawback, and while it provides direct steering on moderate trails, it significantly affects stability on steep and technical descents. The Druid also runs a high-pivot suspension with a rearward axle path, which is fundamentally different to the Amflow's conventional Horst link.

The Loam Wolf reported that the Forbidden eBikes stand above the rest when it comes to climbing traction, with the bike hooking up and winching through climbs with no hint of wheelspin. Combined with that mullet wheel setup as standard, it's a bike that punches well above its travel class on the descents.

As a pair, these two make excellent sense. The Amflow is your lighter, more playful trail weapon, while the Druid CorE would give you a burlier, more confidence-inspiring ride for steeper, rougher terrain.

Enduro magazine rated the Druid CorE as the best all-rounder among DJI-powered eMTBs tested, and @jbrown15 reckons it's a way beefier build than the Amflow, which is exactly what you'd want from a complementary second bike.

One practical note: the S2 comes with a 180mm dropper, which at 5'6" should give you plenty of range. And even the S1 can accommodate a fully slammed 180mm dropper post, so if S2 feels roomy you could drop to S1 (430mm reach) without losing dropper travel.

I've got community data on Druid suspension setup, motor tuning, and owner impressions if you want to dig deeper into either size.
