Why the Yozma IN10 Pro rules the heavy rider budget class

Finding a reliable mid drive dirt bike under two grand is usually an absolute headache. If you spend any time browsing the market you end up sorting through endless cheap hub motor setups or tiny pit bike frames that bottom out the second a full grown adult hops on them. Then the Yozma IN10 Pro showed up at just under $1700 and kinda wrecked the grading curve for everyone else playing in this price tier.

Suspension that actually holds up

What caught our eye immediately was the hardware they bolted onto the frame. Most bikes in this lane cut corners by using standard right side up forks that just can't take abuse on rough trails. Yozma threw an inverted hydraulic fork on the front and paired it with a dedicated nitrogen rear shock. They also equipped it with real 17 inch front and 14 inch rear wheels to keep the trail geometry right where it belongs when digging into deep corners. It's a massive upgrade from the typical cramped geometry that makes you feel like you are riding a circus bike.

But the real selling point here is the massive 330 pound weight capacity. If you weigh north of 250 pounds you already know exactly how bad a typical budget ebike suspension feels when you hit a curb or take a small drop. The Yozma has enough structural clearance and spring travel built directly in from the factory to actually maintain decent compression and rebound. It doesn't constantly feel like the frame is screaming for help under heavy load.

What to know before pushing checkout

It pushes 5500 watts of peak power routed from a heavy 60V battery pack. It definitely pulls hard off the line and they confidently claim a 50 mph top speed right out of the box which we found to be mostly accurate on flat pavement. The only real issue we have with the entire rig relies completely on the controller system. They use a proprietary closed ecosystem firmware. If you are the type of rider who wants to plug a laptop into your bike to tune custom throttle curves or tweak phase amps you are going to be completely out of luck here. You get what they give you.

Ultimately if you just want a solid heavy duty mid drive machine to rip around local trails and you are working with a tight budget, the IN10 Pro gets it done better than almost anything else sitting on the market right now.

The HappyRun F18 is a torque monster with one catch

HappyRun Sports essentially threw everything they had into the F18 specifically to dominate the entry level budget tier. Out on paper this thing looks completely ridiculous when you realize it only costs $1599. It pushes an unreal 6000 watts of peak power directly into the internal gearbox making it arguably the most aggressive mid drive bike available anywhere at that exact price point.

Massive power needs a massive tank

You can't dump 6000 watts of heat through a motor without a huge battery to back it up or you just end up walking the bike home after thirty minutes of aggressive riding. They clearly knew this when designing the rig. The F18 ships standard with a massive 1800Wh cell configuration. It gives you a lot of range to play with even when you are pinning the twist throttle in gear three throwing dirt up. That is a ton of capacity for a bike this light.

On the suspension side they went heavily with a specialized oil spring coilover in the rear. It absorbs loose gravel trails nicely and typically gives a slightly softer overall ride compared to the ultra stiff nitrogen shocks usually thrown on these frames. It feels right at home on rutted out dirt roads.

The thing they left out

The bike absolutely demolishes steep hills with its raw off the line torque, but coming back down those exact same mountainous hills is where things get genuinely tricky. HappyRun intentionally did not include native regenerative braking in their controller geometry. If you are riding down long steep downhill sections you have absolutely no motor braking to rely on. You have to lean entirely on the mechanical hydraulic disc brakes to scrub speed.

Heavy riders over 250 pounds are going to easily burn through the rear brake pads incredibly fast without that electronic motor drag helping out on descents. It is definitely something to keep an eye on to avoid brake fade when things heat up.

At the end of the day the F18 is a total powerhouse relative to its price tag. If you live anywhere flat or you are just looking for crazy acceleration it is a solid buy. Just know that if you spend your weekends dropping down sketchy hills you need to check those brake rotors constantly.
