Strengths:    Quality brakes and an extra light extra smooth ride.

Weaknesses:    Had to change the rear gear cable 3 times in the first month/.

Bottom Line:   
An excellant ride when it works and i strongly recommend it to all professional riders. Sall the XTR gear just improves the quality its a wickid ride when its goin.
Dont buy it unless you have the know how to repair it when it goes wrong

Strengths:    Light, When working, its pretty good

Weaknesses:    It doesn't work too often

Bottom Line:   
When I first bought this bike, I was beside myself with glee. Even when the rear shock spat out all its oil and the pivots wore out, I happily paid the bucks at the local shop for new seals and pivot bearings every three months. After about a year, the rear triangle snapped at the shock mount pinch bolt. I was pissed, but I went ahead and got a warranty replacement rear triangle.
This process went on for another year and a half, only as I started riding more agressively, I broke two more rear traingles and went through a set of bearings every month. Dont even ask about the shock. I bought a Genisis Air shock, which was a waste, since I rode it like that for about five months before I snapped another rear triangle and decided to just ride my hardtail and forget about full suspension

Date Reviewed: June 1, 2001

Strengths:    This is where it all started. The way the shock mounts and the seat tower allows for a more rigid ride. This bike is from 1996, I weigh 200 pounds, I know how to ride and NEVER had a shock blow, cracked the frame or had any complaints. Yes, it is a bit whippy but for a fully suspended bike under 24 pounds, what do you really expect. Horst is a genius when it comes to minimalism - the goal isn't to get down the hill, it is to ride... up, down, over, and through. This bike is nimble and quick and holds up well. For those of you with problems, call Brion LaBelle, he gets stuff out fast. By the way, I just built an Intense Tracer - it is the exact frame, but just built up a bit stronger. Both do well, the AMP is lighter and quicker, the Intense is more solid and screams downhills, YES, I will be riding BOTH for the next few years. To those who cry about the AMP being weak, go get an Intense M1 and some MX gear and go for it..... the AMP requires some finesse.

Weaknesses:    Rear end gets whippy on really hard descents, but the overall ride quality and light weight makes up for it.

Bottom Line:   
This bike is great if you know what it is. Sounds dumb but think about it. Super light, super nimble, lo tech, easy to maintain. This is not for gorilla riders, downhillers, or people who can't pick their lines. If you know how to ride and care for your stuff, then it will last years and keep you happy. Not to mention they are going to be collectable, since Horst doesn't make them any more, he is making big cash on the bed Xtenders for toyota, nissan and ford trucks.

Strengths:    Light, fast, cheap

Weaknesses:    Flexy... frame might be weak...

Bottom Line:   
Hmmmm, this bike is ultra-fast! It climbs well, and it descends decently... now I read some people blowing up the legs on this somewhere, and I read about some dude here cracking the frame... well I guess if rode improperly you could break it, sure, it's lightweight as hell! BUT!, I weigh 190lbs, and I have been dropping this thing off of 5 and 6 foot drops (don't ask why) and I have pics to prove it... I have not broken ANYTHING, and it works just fine... I guess if you buy something so lightweight you really have to respect that fact and be ready to COMPENSATE by riding lightly and landing properly... Look in the photogallery for my pics of me dropping this thing of stairs...

Submitted by Isinuts a Cross Country Rider from Minneapolis, MN

Date Reviewed: April 5, 2000

Strengths:    The lightest (when properly set up) full-suspension rig that doesn't suffer from pedaling feedback.

Weaknesses:    First, you will need a backup bike, because when the shocks or disk breaks blow, or the pivots need rebuilding, you have to send pieces of your bike to California. Second, your "friends" will claim that they could climb and decend as well as you, if only they had a full-suspension bike.

Bottom Line:   
I have ridden around 2000 miles on this bike, and have had the front shocks rebuilt three times, including once when I upgraded from aluminum to carbon fork legs (worth it). The rear shock was rebuilt four times before I got smart and purchased the Risse Genesis shock. The rear disk brake blew once, which required 2 returns to AMP to fix. Each return to AMP will put you out of commission for at least a month, so get a backup bike you really like. This is not a cheap bike, no matter how much you pay for the original parts. I've kept mine running like new, and I'm going to ride until it breaks again. I have the AMP travel case that's escaped airline oversize bag charges three times (but I also was charged, once). Try to put your Specialized FSR S-Works into a suitcase, and see what happens! I'm giving this bike five smokin' spleefs for being the best FS frame money can buy that doesn't have a Specialized logo on it.

Strengths:    Super light, well engineered...

Weaknesses:    Rear flexes slightly, but not bad at all....

Bottom Line:   
This frame (As wasthe wheelset and brakes)was purchase on Marketplace used. It already had the Risse astro5 upgrade on the rear. I built this bike as a race bike 1st, fun bike 2nd. I have a Jamis Team Dakar as a backup, but I find myself wanting to ride the B4 much more now that it is dialed in and the XMO has been rebuilt after breakin. The B4 does have minimal flex, but I know that any sub 5# FS frame is gonna suffer minimal flex. This bike hammers as it sits and will make a great race rig this summer. I am 180# and I am not easy on bikes (Read my reviews on both mongooses I list above) and because of this, I was a bit skeptical when I bought the frame. Thought I was gonna have to take it easy on it and only race the bike. Not TRUE! I am hitting everything as hard on the B4 as I would be on my Jamis, and the bike takes it all on the chin and keeps going. I have less than $1600 invested in this bike and it was the best $1600 I have spent. The bike is 8 speed and has hydraulics and it works great. Frame flex is minimal and the bike handles well. Don't buy it if you plan to free ride, but buy it you are an agressive XC rider or racer. It jumps, climbs and hopps with the best of them. As for a previous posters comment on the FSR XC, well a rider in my group has a 99 modelthat he has replaced the swingarms and bushings on 3 times in the last year. I'd look elsewhere if you are affraid of a loose rear link!

Date Reviewed: August 4, 1999

Strengths:    
light fast cheap


Weaknesses:    
flexy(you get used to it), you WILL have to upgrade the shock


Bottom Line:   
I owned a B-3 for over 3 years. Once I got over the flexy rear end and bought a Risse, life was good. the bike was light and fast. I had problems with AMP customer service in the past, but Brian is a good guy. When I felt the need for a new bike, I purchased a Mtn. Cycle, based on its lateral stiffness. While being only @ a pound heavier, it didn't feel as fast. I sold it and took a decent loss. I then traded my old B-3 in on a new B-4 w/carbon stays. Before I rode it I swapped out the shock w/ my Risse. It flexes less than my B-3 did and feels betteron all terrain. I'll still give the frame a good rating because it seems to be common knowledge that you will have to replace the shock. Just save the old shock so when the Risse needs rebuilt, you can still ride.

Date Reviewed: May 29, 1999

Strengths:    
light, rides good, standover height, affordable if non breaks


Weaknesses:    
seatstays flexes , decals/stickers peeling off and as usual -rear shock


Bottom Line:   
I have some regrets on buying this frame set i should`ve save some more $$$ and bought an fsr xc s-works frame set. anyway, the first time i rode my b4 in the trail i noticed right away that it is light but i also noticed a knocking sound from the rear shock so, i send it back and thinking they`re gonna send me a brand new one instead they just repaired my shock that i send to them , good i have my reliable santa cruz heckler to ride on i didn`t miss any of my scheduled rides (waited almost 3 weeks for my crappy AMP shock) anyway , when i got the rear shock i installed it and went to my local trail right away and guess what...... you`re right the problem is still there, so, what i`m planning right now is just wait till this shock breaks down for good and replace it with a genesis. and as for the frame i have to wait and see- i hope the frame won`t be a problem soon.

Date Reviewed: May 5, 1999

Strengths:    
Light
Rides well when not broken.


Weaknesses:    
Frame is too weak.
Rear shock is a joke


Bottom Line:   
This Bike comes close to hitting the mark but just doesn't reach it.
The frame has cracked twice in the same place (at the head tube/down tube junction). The stock AMP shock is the most poorly designed component I have ever seen.
To top things off Horst Leitner, the owner of the company and designer of the bike, has decided that the replaced components will not be warranteed the year after purchasing the frame. Even though the front triangle is only about 3 months old at this point. I will only have been able to ride the bike for about 10 months. The other 2 lost due to warranty concerns.
This should be right about when the newest one is due to break. I will be consulting a lawyer however and will post another review when this latest issue is resolved.
I have dealt with only one competent employee at AMP and this is Brian LaBelle. It is my advice to him that he jump ship because with such poor designs and lousy policies I don't imagine they will be profitable for long.
I have and will be telling every rider I meet about my dealings with AMP in hopes that they do not suffer the frustrating experience.
Wake up Horst your product isn't the only out there!
This frame gets one chile (because I have to) even though I figure they owe me about twenty.
