BRM100 Mini Dirt Pit Bike 105cc 4-Stroke Off Road for Teens Adults 220 LBS

Gift, person love it

Ordered this bike a few weeks ago and my son & I just got around to assembling it last night with no issues. Everything went together smoothly and the build quality is great for the price. We researched a lot of bikes and pricing as this is my 12 year old son's 1st bike; and so far we are very happy with the OryxEarth bike :) NOTE: it is recommended to add then change the oil (10W-30) after 30 minutes to 1 hour after riding and priming the engine to make sure you flush out any debris or metal grit that might be floating around the engine. We read this in our research and followed the instructions and definitely saw blackened oil and some minor grit during our oil flush. Looking forward to messing around with the governor for some more speed. The bike goes 25 mph right out the box.

It's fun and pretty fast

Nice bike last about a day with out filling up pretty good and reliable very good bike

Around the size you’d expect I guess. I’m 5’9 and leg room isn’t an issue. Unfortunately the switch to turn the engine off on the handle bar is loose and wont tighten, I’m pretty sure it’s somehow broke but that’s not a problem for me at the moment. The throttle was also loose and it would cause it to flip the kill engine switch but I was able to tighten that to fix it. The throttle also has a big dead zone before it actually starts to give it gas which bothers me but doesn’t seem to be a real problem yet. Also I’m not sure if it’s because of user error and I didn’t tighten something enough or what. But when you’re speeding up and getting closer to top speed, something in the front and I wanna say it’s the fender that’s over the wheel. But it makes a violent vibration sometimes and caught me off guard. (EDIT: After 2 months of use I can say that it went away). Putting it together was also pretty easy too. The only thing I really don’t like is where the motor oil goes due to it being in such a tight spot. The bike comes with a squirt bottle I’m assuming to put oil in the oil the clutch but I’m pretty positive it’s not for filling the motor with oil. But it was pretty difficult considering the hole isn’t angled for an easy pour. I ended up using a funnel and it still leaked everywhere. And it didn’t work with the bike flat on the ground so I had to find a way for the front end to sit higher. So just be aware of that difficulty. All in all it seems to be worth it at the moment. Also you can choose any color when purchasing because it arrives with each of the colored stickers for you to choose from. Update found 2 spots that require 2 screws to keep the gas tank attached to the engine. Ironically it’s the 2 screws I thought were backups and not needed anymore since that wasn’t included in the instructions. Doesn’t cause rattling or anything without the screws but does cause it to be loose which is unsettling and risky. Edit: I’ve had this bike for about 2 months now and found a few problems. First of all, the gas tank, which I haven’t figured out yet, will randomly start leaking gas out of the cap. Mind you I tighten it a lot. It’ll randomly start leaking gas out of nowhere but hasn’t caused any serious issue other than a slight leaks every now and then. Secondly, when running at half throttle or around. The bike will run rough and jumpy. And last, I’ve noticed that if I got from full throttle and even slowly let off throttle to a idle and coast that the engine sometimes likes to turn off while riding (Only when let off the gas and coasting). It’s only happened twice and would start back up after a few cranks. To counter those problems, I’ve only filled up my 2.5 gal gas can twice. This bike is extremely gas efficient and will run forever. To conclude it’s still definitely worth the purchase but it does definitely need to be kept up with and maintained.

Son loves bike but did some upgrades to it!

Perfect size for my kids (13 & 9 I bought 2). Assembly was easy. My 13 yr old did it. They ride these bikes every day almost and have a blast. Well worth the money. They came with multiple colored decals as well. After not riding all winter they started up again a week ago and read the update UPDATE: The chain constantly comes off. It is way to loose and the adjustment isn’t near enough. I am changing my 5 star to 1star due to the headache. About 5 min of ride time and have to put the chain back on. I wouldn’t buy this again and regret my purchase

The little thing is awesome
