- An all mountain trail + downhill mid drive powered electric bike with 150 mm air suspension, rigid thru axles (15 mm front 142 x 12 mm rear)
- Impressive 20 speed drivetrain with quality Shimano Deore XT groupset, capable Shimano M615 hydraulic disc brakes (203 mm front 180 mm rear)
- Ebike specific frame with internally routed cables and wires, custom motor interface and downtube side-slide battery keeps weight low and center for balance
- No shift sensing with the Yamaha drive system but it relies more on torque so easing off while pedaling reduces mashing, large heavier charging unit
The ALLMTN group is one of my favorite SDURO (Yamaha powered) electric bike lines from Haibike. It comes in four trim levels with varying levels of component groupsets and I tested the RC which is one step up from the bottom, priced at $4,299. That’s $600 more than the entry level SL model and the biggest difference is a 20 speed drivetrain vs. just 10 on the SL. For my ride test I climbed a very steep dirt path and those extra gears really came in handy. I wasn’t sure how shifting would perform because the Yamaha system does not offer shift detection the way that the more expensive XDURO (Bosch powered) Haibikes do. What I’ve found during my ride tests is that Yamaha relies more on torque and seems to have a shorter range of RPM which results in less mashing if you ease off while shifting but requires more shifting to happen in order to really leverage the motor’s power.
Driving this ebike is a 250 watt nominal… 500 watt peak internally geared motor that is custom mounted to the area of the frame normally reserved for the bottom bracket tube. Haibike touts their Aluminum frames as being hydroformed with a gravity cast interface at the motor mount. Basically, it looks beautiful, is strong and saves weight. What you get out is up to 80 Newton meters of torque… which is a lot for a production electric bike that follows US law for classification as a Class 1 model (permissible for use in the most environments and trials). There’s no throttle here, you just pick an assist level, pedal and the motor automatically kicks on based on your cadence and pedal torque. I had no issues climbing and was able to use the lowest two gears to reach my destination at the top of a peak on the outskirts of Simi Valley, CA where some other ebikes had struggled in days prior. The one complaint I had (and this applies for all Yamaha powered ebikes I’ve tried) is that in order to get full power from the motor I had to slow my cadence and often shifted up. With similarly specced Bosch powered models I was able to spin a bit faster while getting similar power.
Powering the bike is an impressive 36 volt 11 amp hour battery that slides in from the side and can be charged on or off the frame. The long slim design and unique mounting feature means the top tube on the bike can angle down more delivering a lower stand over height. This makes the bike accessible and when combined with the four frame size options, means more people can handle and enjoy it. Another feature I liked was the seat post dropper with remote (you can click a button, sit down and the seat post will slide down). This is super useful for transitioning from spinning on smooth terrain to bounding across bumpy terrain or bombing down a large hill. A high saddle can interfere with your leg motion to absorb bumps and kick you in the butt painfully if you drop a large bump or rock and squat suddenly.
A couple of other highlights with this and all ALLMTN models are the low-rise bars and negative-angle stem designed to protect the LCD display. The console itself is removable so you could pop it off on rough descents… just in case. Stiff thru-axles are used front and rear with 15 mm and 12 mm respectively and that’s part of what makes this a capable “all mountan” platform for use on challenging downhill terrain. Both suspension elements use air on the RC model so they weigh less and the bike comes in at ~51 lbs which is decent, both suspension shocks offer quick release and rebound adjust and the fork has remote lockout. My favorite part of this model is the bike itself, it feels great off-road and the brakes, while not top of the line, were solid on my short descent. There’s plenty of room to upgrade with the ALLMTN Pro and Plus models but the cost is quite high. I think I’d consider switching to the XDURO Bosch powered drive system for the extra money first because it suites me more… I have sensitive knees and prefer to spin faster vs. harder pressure with slow cadence. All Haibike ALLMTN models are limited to 20 mph assisted which is easy to hit on paved surfaces but feels thrilling off-road or while climbing medium grades.
- Haibike is touting their Yamaha powered electric bikes as offering “uncompromising performance” geared for a younger demographic, zero cadence assist is meant to be more immediate (verses the Bosch Centerdrive which requires 20 rpm for the motor to kick in), in my experience both systems start extremely quickly and Yamaha is more torque responsive with a stronger but slower feel
- With the ALLMTN series (anything above the SL) you get two front chain rings for a total of 20 gears, this offers a wider range of operation 455% vs. 420% and I could feel it when climbing the steepest inclines during my ride test
- The Selle Royal saddle matches the frame, feels pretty good (but firm for active riding) and has an integrated light or bag clip for Selle Royal compatible accessories
- The display panel is large, easy to read, backlit and removable! I’d probably take it off when doing tricky downhill stuff in case of a crash), I like that the button pad is easy to reach, well sealed and has an integrated Micro USB port for charging accessories
- The Yamaha mid-drive motor operates fairly quietly in high and mid level gears (when it’s not spinning super fast)
- You can charge the battery pack on or off the frame and since it slides on from the side vs. straight down like Bosch and other brands, it allows the top tube of the frame to angle down lower for more accommodating stand over height
- Fun color scheme, the matte black with blue and fluorescent yellow accents looks rad and even the battery decals, saddle and fork are color matched!
- Nice suspension fork with 150 mm travel, a stiff 15 mm thru axle, remote lockout and rebound adjust to handle a wide variety of terrain
- The rear suspension is also light weight air and has a rebound adjust with two settings that almost behaved like a light lockout
- Excellent weight distribution, the motor and battery are positioned low and center improving handling, both wheels have quick release for easier transport or trail maintenance and the motor is well protected with a replaceable plastic skidplate (also color matched!)
- Offered in four frame sizes for improved fit whether you’re tall or short and if you’re female check out the similar FullLife model from Haibike for a different color scheme and shorter reach or downgrade to hardtale with the HardLife models
- Limited motor speed range, I found that when switching down to lower gears the motor support dropped out significantly (even in the highest pedal assist mode) because it relies so heavily on torque as an input, this was a bummer when approaching hills at high speed riding off-road
- No shift sensing or shift detection built into the drive system, this could lead to more mashing, banging and premature wear on the chain, cassette and derailleur
- Large battery charger with cables that don’t come unplugged so it’s extra long even when the cables are tied up, it also weighs more than some other chargers I’ve seen
- I found that the battery pack can rattle a bit at times and that you really need to make sure it’s clicked in before riding off, you could turn and remove the key but then push to hear the click of the battery
