Motobecane HAL eBoost Pro 2020 Electric Mountain Bike Review

By Rob Robinette


Spoiler: I love this bike.

Full suspension electric mountain bike with Shimano E8000 motor and running gear, big 504 amp hour battery, 27.5" wheels, RockShox 3-way adjustable Pike fork, RockShox 2-way adjustable rear shock, 1x11 gearing, Boost (wide hub) through axles, hydraulic disc brakes and dropper seatpost with internal routed cable for left thumb actuation. Without the electric motor this bike would be a top level mountain bike, with the motor it becomes something amazing. The bike is also compatible with 29 inch wheels.

I put a couple of hundred miles on a KTM electric mountain bike in Hungary in 2019 and really liked it. It was a $6000+ bike but I didn't care--I wanted one for my own. When I got home to the USA I started searching and was disappointed to find KTM doesn't sell their electric bikes here so the search continued for a top-level eMountain Bike. I ended up buying an Aventon Pace 500 street cruiser style electric bike and love it. I put 1000 miles on it in the first four months and I lost 25lbs due to the exercise and fresh air. I got so into shape I decided to get a non-electric road bike and ended up with a BikesDirect.com Motobecane Immortal Disc Pro SL carbon fiber gravel bike. It was an amazing value and I put 1000 miles on it in about four months too.

When it was time to replace my 1996 Cannondale Super V 900 full suspension mountain bike I went to BikesDirect.com again but I also reviewed all other popular electric mountain bikes. I believe in "buy once, cry once" so I wanted a premium bike with high level components and the Motobecane HAL (highly active link) eBoost Pro fit the bill perfectly. The price difference between the HAL eBoost Pro and other comparable top-of-the-line ebikes is pretty shocking. The competition started at around $5,500 and went up.

The HAL eBoost Pro Shimano E8000 motor and running gear are among the best available along with the RockShox Pike front fork and RockShox Monarch rear shock. The frame is a high quality unit made in the same Taiwan factory that almost all world-class bikes--normal and ebike--are made. It's a very capable mountain bike and at 48lbs it's as light as any other electric mountain bike.

Motobecane HAL eBoost Pro

The RockShox Pike front fork is adjustable for air pressure, rebound and low speed compression. The front fork and the rear wheel have 140mm (5.5") of travel. The rear RockShox shock is adjustable for air pressure and rebound. It also has a lockout lever when you'd prefer a hard tail. The 2.8" wide tires run at 35psi.

I ordered the bike  from BikesDirect.com on Wednesday and it was delivered six days later by FedEx. The bike arrived without a single scratch. I took my time assembling it in about two hours. Assembly requires installing the seatpost (seat already attached), front brake disc, front wheel, handlebar and pedals. The steering stem had one spacer above it so I removed the stem and placed the spacer below the stem to get the handle bar as high as possible. The bike looks like a freakin' sex machine.


Well Packed With No Damage

The bike didn't have a single scratch. Nice job BikesDirect.com.

Putting It Together

Don't remove the front disc caliper plastic spacer until after the caliper is installed loosely on the fork, the front brake disc has been installed and the wheel is ready to go on. With the wheel and brake disc installed and while applying the front brake, tighten the caliper bolts. This will center the caliper on the disc. I was really surprised by how light the big fat wheels and tires were. They will be even lighter when I pull the tubes and go tubeless.


Dropper Seatpost Install

This is the most difficult part of the bike assembly. To install the seatpost you may have to pivot the motor down to allow the seatpost dropper cable to slide past the motor. Before dropping the motor see if you can move the seatpost cable by pulling the cable out of the frame (exit near the handlebar) while pushing the cable up at the base of the shock. Just try to move it a little. An owner of a HAL eBoost Elite (Shimano E7000 motor) was able to pull the seatpost cable slack this way without loosening the motor. If the cable moves then go ahead and connect the seatpost cable to the seatpost. If you can't get the cable to move then see the pics below to pivot the motor down.

Pivot The Motor

Remove the two small bolts holding the motor front skid plate. Loosen the two upper-forward motor bolts and remove the others. The motor bolts take a Torx T-30 security bit.

You have to remove the 4 chainring bolts to access 2 of the motor bolts. The chainring bolts take a Torx T-25 security bit. You do not need to remove the crank to get to the motor bolts. The motor only needs to drop an inch or so to allow the cable to slide. Get the cable connected to the seatpost actuator then pull on the dropper cable where it exits the frame near the handlebar. Lower the seatpost into position as you pull the cable.

You'll have to trim the metal part of the cable at the seatpost end and adjust the cable end barrel to fit the seatpost actuator. The barrel is clamped to the cable with a small screw that takes a hex key to adjust. Make sure the seat thumb lever releases the seatpost before inserting the seatpost into the bike frame. Pull the slack as you insert the seatpost and set the seatpost at your desired height. The seatpost has a mark for the minimum seatpost insertion level. Start high and then lower the seatpost to your desired final setting.



Spoke Tension Chart

I use the Park Tool TM-1 Spoke Tension Meter to check and adjust spoke tension. Since 25 (120kgf) is max I plan to set spokes to 23 (96kgf).

The WTB rims are tubeless compatible but need tubeless tape to seal. 1" wide Gorilla Tape works great to seal the rims. To go tubeless I will remove the tubes, install the Gorilla Tape, install tubeless Presta valves and add 4oz of Stan's No Tubes Sealant to each tire.

I added a $13 RockShox front fender to protect the fork tubes and an Elemnt Bolt bike computer with GPS track, speed, cadence and heart rate sensors. I also replaced the included pedals with some thin, lightweight aluminum Fooker mountain bike pedals. Other than that the bike was just about perfect for my needs.

I used the Shimano E Tube app on my Droid phone to update the controller firmware and tune the three assist levels. It connects to the bike controller by BlueTooth. The RockShox Trailhead app can help dial in suspension tuning including initial air pressure for the fork and shock and initial rebound settings. I highly recommend you use the app and adjust the air pressure for your weight. If you don't the bike may sag too much and reduce frame and pedal clearance over obstacles. If you don't have a suspension air pump then it's worth it to have your local bike shop do it for you.

Shimano E8000 controller at right, Elemnt Bolt bike computer added at top. The Bolt monitors and records GPS track, speed, distance, pedaling cadence, heart rate and calories burned and uploads workouts to Strava.

 

Frame Made In Taiwan

The fork and rear shock have red o-rings to help you set sag and monitor stroke length and bottoming. Remove the cap at the top of the left (right in picture) fork tube to access the air valve to adjust air pressure. Low speed compression is adjusted using the knob at the top of the right (left in picture) fork tube. Rebound is adjusted using a knob at the bottom of the fork leg.

P.S. I have no affiliation with BikesDirect.com, I'm just a very happy customer.

HAL eBoost Pro Specs From BikesDirect.com

Shimano E Tube app can tune the bike controller and adjust the three assist levels.
RockShox Trailhead app can help dial in suspension tuning.
For tubeless conversion you only need to tape the rims, add two tubeless Schrader valves and 4oz of Stan's Sealant per tire. The rims are "tubeless compatible" and the tires are "tubeless ready" but still need sealant.

Compatible with 27+ or 29er wheels and tires.
The HAL eBoost frames have 140mm (5.5") Travel and a rear tire clearance up to 96mm (3.78"). The Rockshox Pike Forks have 81mm (3.19") clearance on the front.
The HAL eBoost is a Boost spacing mountain bike. Boost is a new dropout standard designed to widen the hubs on the previous standard MTB spacing wheels. The rear axle is wider by 6mm to 148mm and the front axle by 10mm to 110mm. Wider flanges = wider bracing angle for spokes = a stronger and stiffer wheel. Allows the use of 29er wheels with higher strength and stiffness for top performance.
