About the Micro-B

TLR Champion Race Inspired

The Losi Micro-B 1/24 RTR 2WD Buggy captures the excitement of RC racing in a compact, highly maneuverable package that’s small enough to run almost anywhere. Inspired by TLR’s World Champion buggy, this micro-sized racer delivers big performance and agility. Whether you’re racing in your living room or on a homemade track, the Micro-B’s precision engineering, compact size, and TLR-inspired design make it an ideal choice for both casual RC enthusiasts and those looking to share their passion for racing with friends and family. Its RTR (Ready-To-Run) design means no additional accessories are needed, making it an easy and budget-friendly entry point into the RC world.

Performance Oriented Components

The Micro-B features a black-anodized aluminum chassis, setting a higher standard for micro RC vehicles with its rigid, durable construction. This chassis is designed with front caster kick and side bends to offer superior strength, ensuring it can withstand the bumps and jumps of intense racing. Paired with fully adjustable oil-filled shocks, the buggy delivers excellent handling and a smooth ride over various surfaces. The Pro-Line Racing body, wheels, and tires give it an authentic look and performance edge, reminiscent of full-scale race-winning designs, adding to the realism and enhancing your racing experience.

Electronics & Drivetrain

At the heart of the Losi Micro-B is its powerful Spektrum 350mAh LiPo battery and fully proportional electronics, allowing for precise control and speeds of 13+ mph — insane for a vehicle of this size! The Spektrum SLT2 2.4GHz radio ensures interference-free racing, while a throttle limiter provides “rookie mode” settings for safe learning at 50% or 75% speed.

liam martens Wednesday, Oct 2 2024 (12 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Here’s a review from someone who actually has this little beast.
The motor is smaller than most minis. But stock, it’s plenty fast for Mini-z and even mini-b/t tracks. Jumps beautifully, handles like a dream. Like anything, could benefit from personal tuning, but out of the box it’s a real performer. The 7mm hexes mean you can use scx24/fcx24 wheels and tires (definitely recommend 50mm OD or less to save the factory electronics).
Long story short, get it. Best $100 I’ve spent in a long time, and the aftermarket is only going to make them more awesome 5 customers found this review helpful. George Irwin Verified Owner Sunday, Oct 6 2024 (12 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) WOW! Being in the RC hobby since the early 1980s I am really impressed with this Micro B. Videos don’t do it justice. Don’t let the tiny size fool you. Even with the transmitter set on 50% setting it moves out. Switch it to 100%, it’s on and gone. Gill Sr is looking down and smiling. 3 customers found this review helpful. Jason Verified Owner Friday, Oct 4 2024 (12 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Fun buggy for inside the house. I keep it on an end table next to the couch. I have been using it a lot off and on while watching TV. It does slide around a lot on hardwood floors on 100% throttle setting, 50% setting is about perfect on the wood floors. Get one! 3 customers found this review helpful. C. Stump Verified Owner Monday, Oct 7 2024 (12 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Alright everyone listen up. I ordered 2 of these bad boys and it is absolutely worth it. I haven’t been into R/C in years but these little dudes are amazing. Quality, fast delivery, what more could you ask for? The speed is amazing for its size, 50% is fun, 75% perfect speed and handling, 100% stupid fast about uncontrollable!
Not gonna lie I love them so much I ordered 1 more to keep in the box or use for parts since who knows when extra batteries or stock will be available.
LOSI hit an absolute HOME RUN with this one. Do your self a favor and order 2, not 1 but 2.!! 2 customers found this review helpful. Sanka Friday, Sep 19 2025 (1 week ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Late to the game, but I can see why it’s always sold out. The mini-b is ok because there is much stiffer competition. This micro stands alone and is fun. Makes every track on your patio or living room feel like Monza instead of Monaco. Many indoor sections I can go flat out!
Just scrub the tires first to hook up on wooden floors. Matt Triefenabach Verified Owner Friday, Aug 15 2025 (6 weeks ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Best money I have spent in awhile! Perfect for beginners and experienced alike. Keith Walker Verified Owner Monday, Apr 7 2025 (6 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) I have ordered both color options of the micro b and other items from amainhobbies. Products always arrive in A1 condition and function flawlessly. Amain shines when it comes to their shipping. Everything has managed to make an early arrival and packaging looks good as well. Customer service is great. Will continue to use for all RC purchases! ?? Marco Mandelli Verified Owner Tuesday, Apr 1 2025 (6 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Amazing Losi and amazing Amain Hobbies; very good service… i’ll back soon! Thomas Schellenberg Verified Owner Friday, Mar 21 2025 (6 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Fun little car. Can’t wait to put some upgrades to make it even better Shannon Booth Verified Owner Saturday, Mar 15 2025 (6 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Great little car nice to have for in the house when the weather isn’t ideal for outside fun! Aaron Mendoza Verified Owner Tuesday, Mar 11 2025 (7 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) The Buggy is a great product. It deserves 5 stars. However, the reason for 4 stars is the shipping. I have ordered some other items as well from your company and all of the orders have taken forever to arrive. I would highly recommend you use other shipping methods like fedex or ups. I barely received the first item I ordered yesterday, that has been 12 days from the date of order.It was in the usps indianapolis facility for almost 4 days. The term snail mail is a under statement. I have ordered approximately 2500.00 worth of rc cars and trucks in the last month and choose to go with Horizon hobby due to their fast shipping. Prices are pretty much the same, but they arrive within 3 days. I do like the selection you have, but the only way Ill order more from your company would be if horizon or amazon doesnt have it. I stopped buying stuff on ebay because of the post office. everyone ships with them for some reason.
Either way, I do like the Micro-B Mishal Jackson Verified Owner Saturday, Mar 8 2025 (7 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) The absolute most fun you can have indoors by far. Great jumping, racing or indoor bashing. It’s durable and extremely quick. 50% throttle is more than enough for a good time and a competitive high octane racing experience!! So fun my boys want two of their own! Justin Lewis Wednesday, Mar 5 2025 (7 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Awesome job Losi. Such a fun little indoor car. Plenty fast. Wayne Beardsley Verified Owner Thursday, Oct 24 2024 (11 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) These little buggies are so much fun and pretty fast write out of the box. I live in Richmond Virginia and lucky to have a hobby shop that has a carpet track in the store and these cars hook up perfect. I look forward to running with other buggies and testing on jumps as well. They handled surprisingly very well. I wish there were other color options then white and silver but I painted some touches so it will stand out. Losi did a great job with this one. James Burke Verified Owner Monday, Oct 21 2024 (11 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Absolutely disappointing. I didn’t even get two full charges out of this before the motor stopped working. At first I thought it was the usb charger that came with it being faulty, but after trying it on my higher end charger and making sure the battery held a charge I’m not getting anything other than the servo to function. No throttle. Perhaps it’s some wiring issue, but it hasn’t even been used outside before breaking.
I normally don’t complain about stuff, but I expect more from Losi. 1 of 2 customers found this review helpful. Bryon Nuvill Verified Owner Sunday, Oct 20 2024 (11 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) This thing is a blast, it’s hard to handle on Formica floors but fast a heck on rugs, I love it Eric Switzer Verified Owner Thursday, Oct 17 2024 (11 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Great job losi, u did it again, love these things …. they handle so well, and long lasting battery life. My little girl and I have a blast. I bult a track in our basement for them as well ! Dustin Karrick Verified Owner Tuesday, Oct 15 2024 (11 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Outstanding little cars. Tons of fun. Fast shipping. Original 1/36th scale were out when I was a teenager. These came out on my birthday. Seemed like a sign.
Just wish there were more tire options. The rear fit on the front. Put rear on the front/rear and handling is amazing on carpet. Thaddeus Brown Verified Owner Thursday, Mar 13 2025 (7 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) Use a better shipping company. Usps is now 7 days late with my shipment of my micro b. Most likely will be ordering upgrades through another company due to shipping issues.. besides that I’ve used before and was ordering my own. For the size they are impressive. 0 of 1 customers found this review helpful. Me Verified Owner Saturday, Mar 1 2025 (7 months ago) Losi Micro-B 1/24 RTR 2WD Buggy (Silver) I gave 4 stars because amain shipping is the worst never arrives on time. The product is top notch. Losi is awesome!! 0 of 1 customers found this review helpful. View all reviews
