OHM Sport E-Bike Review

This is a high quality speed pedelec with very good accessories, including aluminum fenders, integrated Supernova lights, a removable color LCD display, and regenerative braking.

The OHM sport e-bike is very well balanced, especially for a hub-motor electric bike. The air fork, hollow-spindle bottom bracket, and upgraded alloy frame keep the weight down. It also rides super quiet.

It’s only available in black, but the motor, wires, and semi-integrated battery pack match beautifully and blend in, larger Super Moto-X tires improve traction and look cool.

The powerful hydraulic disc brakes makes for great stopping power and the right brake lever initiates regenerative braking, the BionX system offers four regen ride modes.

The OHM Sport does come with a high quality rack and 70 mm wide Aluminum alloy fenders which offer great utility for daily distance rides or light trail riding through dirt and mud, you’d be marveled at how quiet they are and that they are able to contain bottle cage bosses onto the seat tube (for fluids, a folding lock, or mini pump accessory).

Let’s not forget the integrated lights from Supernova and this one uses the premium M99 model headlight with day and night sensor for automatic switching between running and bright mode. The backlight has five led’s and is protected by the rack.

This e-bike’s control is easily workable and accessible including the mini button ring near the right grip, the compact transflective color LCD panel, or the smart phone app, being able to remove the display for parking (to reduce wear and tampering) is fantastic.

There are four frame sizes meaning you can get an appropriate fit for your body type. The stem, handlebar, and crank arms vary between the four sizes. The top tube is angled down to make the bike easier to mount and stand over.

Considering how sturdy and well accessorized this e-bike is, anyone will be amazed with the 56.5 lb weight (only one pound heavier than the OHM Urban). It’s got sturdy metal lights, large tires, a high-capacity battery, and a powerful gearless motor. But things like magnesium pedals, a minimalist kickstand, hollow spindle bottom bracket, and air fork all make a difference.

The all-black and grey color combo looks great with the battery casing, motor hub, and wires all blending in. The decals match are minimalist in design and really cool (especially under the downtube) vs. flashy, and OHM also includes some touchup paint to keep it looking nice.

First seeing the bike, and knowing that the BionX D-Series motor weighs ~8.8 lbs, you’d expect it to be rear-heavy but when you lift it just in front of the saddle nose it will tip forward vs. back, It’s very well balanced and the weight is all kept low for improved handling vs. a rack battery.

There are comfortable touch points including locking ergonomic grips, finger-adjustable brake levers, a sporty Ergon gel saddle, and wider Schwalbe tires with a medium-range pressure recommendation.

Safety is important, and since this bike is black, I appreciate the reflective graphics on the tires and and bright integrated lights, You’d also like the sturdy thru-axle on the fork with Boost and large tapered head tube for stable riding.

Riding this e-bike will always get you feeling good, it’s more polished, quiet and balanced than a lot of others… it’s also one of the few that even offer a throttle mode which is fun to use.

Although regenerative braking doesn’t put much power back into the battery, it does reduce wear on brake pads and can be used to simulate climbing with the four minus levels on the BionX system.

The present unique design of the hub motor casing, being relatively slim but tall, allows for the spokes to connect at the hub vs. the outside of the hub motor and this allows them to flex naturally providing a wanted level of comfort and performance that most other hub motor e-bikes lack, the greater air volume inside the hub allows it to cool more efficiently.

The battery pack clicks in from the left side vs. down from the top which means it won’t bump into the frame as easily when mounting or dismounting and the top tube can be lower. It’s a good thing that the battery is rated against dust and water, uses a fast charger, can be filled on or off the bike, has several rubber pads to reduce vibration, and even has a touch-activated capacity indicator (where the charger plugs in) it lights up green at 70%+, orange between 20% and 70%, and red when below 20%.

After a few minutes of inactivity, the display panel will automatically power of. It has lots of settings where you can change brightness, units, etc. to make it fit your preferences and style.

Larger 180 mm hydraulic disc brakes provide the kind of stopping power that mountain bikers need, so it’s cool to have them on a sporty trail bike here, specifically because it weighs more and can be switched to 28 mph Class 3 if you want (I think you can ask OHM to do this and change the Class sticker before it’s shipped to you).

Shimano Deore XT is a mid to high-level drivetrain and ten speeds is enough to let you climb and reach higher speeds comfortably. Though the larger 48 tooth chainring is setup more for speed, there are times where you’ll need to ride in the absolute lowest gear because of a hilly terrain. It’s good that the derailleur has a one way clutch to reduce chain bounce (the little grey lever, point it up to tighten the chain).

The chainring has a plastic inner guide to reduce drops, it’s not going to keep your pants or a skirt as clean as a chain guide or chain cover but it reduces weight and is practical.

The cockpit is relatively clean because of how the display and light are mounted, the handlebar clamp positions the large Supernova light below the display and they are both at the center for optimal use.
