I have now completed two weeks of commuting to work and I thought it was time to report again on my impressions of my 49 diamond frame Agattu.

Summary of round-trip commute:
5 miles with approx 2.5 miles of very steep hills ( 1 in 5 to 1 in 10)

1.Battery Range and power

I have now fully conditioned the battery with two complete discharges. I found that the battery will last on a full charge for 5days ( in other words, a working week). Even on flashing red lights, I managed another full round trip. In terms of power assistance, I am getting used to the way that it works but it does take a bit of time. On the steepest parts of hills I find that 3rd or 4th are best for optimum assistance. The more you push, the more you are assisted. The great thing is, if you start to get tired and reduce your effort for three or four pedals, the motor gives you a boost and it feels like someone has kindly run up behind you and given the bike a shove. I am still struggling a little with hill starts with the power on. When I stop on a narrow part of the hill, to let an oncoming car past, I find that when I start again, the motor propels me wobbling out into the middle of the road. I am still unsure about how to deal with this.

2.Gears

I am now getting used to the gears and changing more effectively (with slight pauses between). The gears have now worked themselves in and change smooth with no rattling or reluctance. Although the throttle style gear change was a little odd at first, it is very user friendly after a little while. 6 and 7 are indeed a little light but I don’t think it is worth changing the rear sprocket as I am so often on hills and rarely on the flat.

3. Bike Quality
Superb overall, I can’t really fault it; German manufacturing at its brilliant best. I think the weight is still a bit of an issue if you have to haul it up and about . I have to get it up 15 steps at my house and into an awkward porch. At the end of a tiring day and the cycle home, I’d rather not bother. However, the removal of the battery and the panniers helps reduce the weight when lifting.

Lights – Excellent, though it took me a wee while to work out that the dynamo front light will stop when you stop, whereas the rear light stays lit for about two minutes when at a standstill. ( I thought the front light was broken becuae when I stopped to check it , it was always out (DOH!!!)

Front shocks- Very good though very bouncy and not very absorbent, so you have to be careful when careering down pothole riddled British roads. You may find yourself divorced from your bike and head first in the field next door.

Brakes- Very sensitive . On my first day, I just about went over the handlebars as I stopped at a junction. But you get used to them very quickly and they are incredibly responsive.

Frame size- I am 5 foot 8 with an inside leg of 30 inches. I find the 49 inch diamond frame is just OK. The saddle is on the lowest setting and I can put my toes on the ground. At times it can be a little bit awkward if you have to stop suddenly. Also, unfortunately, the bike is too big for my wife . I say unfortunately… but if you wish to share with a shorter partner you should consider a smaller frame.

A minor gripe is that the gear cable keeps slipping out of its socket on the handle bar .I’m sure someone can tell me how to adjust this and it is not a design fault. I’m also having a problem maintaining the tightness on the handlebar/frame junction. I noticed that the handlebars were wobbling a little after about a week of commuting. I tightened with an allen key but after a day it had loosened slightly again. Again, I think I need advice on this.

4. Cycling experience
Superb. I have used the bike both as a pedelec and as an ordinary bike and it handles very well. Extremely comfortable and easy to manoeuvre despite its weight. At first, on my steep hill commute I think I was trying too hard, pushing the bike up the hill. Also, I hadn’t cycled regularly for a few years, and after the first week, I thought I was going to keel over. I was beginning to think I had made a mistake buying the bike, underestimating how much effort was required to get myself up the steep hills of Bath. However, the second week has been a lot better. As I become accustomed to the bike, I have found that the best method is a combination of muscle power (rewarded by more electric power) and then slacking off a little to rest , allowing the motor to help you up the hill. It must be said though, if you are looking for a free ride, this is not the bike for you. But a truly wonderful cycling experience nevertheless.

5. 50cycles and after sales service
There is no need to worry about 50cycles. They have been nothing short of brilliant. I accidentally broke my chain guard and they replaced free of charge within two days. Lloyd, the technician is a wizard who will help resolve the simplest to the most complex problems. He has also sorted me out with various queries on the phone and email.

Total Score 9.5 out of 10

Hope this is helpful ( good to hear how other commuters are doing)

I would have expected these issues to be checked at the PDI?
Do you mean the outer gear cable, don't quite understand how this could come loose and the gears still fuction properly?
As for the handlebars, in which direction are they wobbling, side to side or up and down?

Do you mean the outer cable jumps its housing on the gear shifter - this happened to me and you appear to lose a gear, 6 is really 7 etc. I thought this was a one off. I had the same thing with the handlebars, which I undid and retightened. One issue I have had is with the grips - the right hand side has disintegrated (layer after layer keeps peeling off) after 25 odd miles - shame they looked quality items.

I can see there might be problem shooting off into the road when you start off as in the low gears it is quite frisky. Have you tried starting in medium power mode or in the next higher gear?

I checked my handlebars this morning and noticed a slight wobble. My problem was the stem clamp which needed tightening by about half a turn. Obviously nuts and bolts can work loose, but this shoudn't happen after a couple of weeks:confused:
My left handlebar grip is peeling which I thought was strange, but that is after 1200 miles, but interesting to read it is happening to someone else.

One little tip. When you ride with the key in the rear wheel lock and the battery lock ley is on the same ring , it jiggles against the frame and will eventually wear through the paint. I have put a 1" strip of black insulating tape on that area of the frame to prevent this. As the frame is black in that area it is hardly noticeable.

Hi Folks, thanks for the feedback..
What I mean is the gear cable occassionally slips out of its housing by the right grip ( it doesn't disconnect) but it makes 7 impossible to engage (until I notice and pop it back in its socket. I have to say it hasn't done it for a while so it may have run itself in.The handlebars are wobbling horizontally in the black socket that connects to the silver vertical steering pole. (if you get my drift) . I have tightened with an allen key but it has loosened slightly again. There's a load of German with a warning on the junction but I can't understand what it says. There's also information about torque but again I can't follow.
My left grip is alo beginning to show signs of disintegration.. not sure why or how to stop it.

These handgrip problem are strange. The review one I rode last year had completed 140 miles before I received it, and at the end of my mileage there was no sign of deterioration of any kind.

Seems like a later problem batch.

The cable jumping is the same as I had and I was hoping was a one off, although to be fair it is quite easy to fix.

With the handlebars have you tried undoing and re-tightening? I suppose the next step would be to use some locktite on the threads. Torque settings are difficult if you don't have a torque wrench but you can normally get a feel for how tight you need to go and if you are using an allen key then the leverage is quite limited anyway. I'll see if mine come undone in the next week.

I have spent the weekend doing various modifications to turn it into my ideal commuting pedelec. New handlebars and the gearing mod with 18T back sprocket were the main changes. I will do the weekly commute and see how I get on.

The grips will have to be replaced probably with these Velo Ergogel D3 Lock Handlebar Grips Ergon they nearly match.

I got mine at the end of November which I assume was the 1st batch to be sold.
The left hand grip has peeled slightly, I thought it was just me, but clearly not. It's a pity as they are nice comfotable grips, not the end of the world though.

Thanks Harry for the help.. I'll have a go at loosening and re-tightening the wobbly handlebars. The grips should be under the warranty, though until they completely fall apart, it's not worth worrying about.

Great Summary musicbooks. It really matches my experiences (and learning!) with the bike. Thanks for the tip about the front light! i had no idea! There's an off button on the front light anyone know what that does?

Re Forks and handling. I'm quite pleased with the forks although I've never had sussy forks before. I have them set at the minimum travel and theyre not too squishy on the flat but handle brilliantly on fast descents, which is where my steering disapears on a normal bike. I also find it eats small bumps and lumps in the road. Of course that upright , sat back, riding style that is just so comfy is the worst style in the world to get over big holes , so this bike will never handle all terrain.

Starting should come with a hazard warning! Its the best feature of a pedelec and the most unexpected! I've tried 3 strategies to stop myself being propelled into the middle of the road. On a hill i take the gear down very low say 2, which means much less power gets sent through and the start is more controlled. On the flat i do one of 2 things. One is to 'twitch', just to give the pedal a bit of a push, but dont follow through. Once the bike is under control, i then follow through. The other is to flatten the pedals before starting. So with a normal bike, you have the pedal upright, so that you can achieve maximum leverage and continued power in your first stroke. By flattening the pedals, the first stroke only provides very gentle power. I think this is the best way of doing it, but it will take some practice.

Any guidance from other agattu or lafree riders on the starting issue?

I'm really pleased your commutes working out! I commute on a conventional bike and shower at work, but for me the Agattu has replaced the car for 'other trips'. Which is exactly what i bought it for!

Just for reference anyone!
The 57cm Crossbar Agattu has now popped up on the 50cycles website as
"In Stock".
Thats good news !

Regards Bob.

Ezee Forza surge at lights

The Forza will surge forwards when seting off if allowed but I use a combination of pedel pressure to activate the battery power and brakes to hold the bike back. I find that this allows me to balance standing upright on the pedals just like Reg Harris (a name most on this site should remember). I see this as an asset rather than a problem!

Great news John.. though not so good that you have to collect
They're coming in thick and fast now.. It'll be interesting to see how the gents compares with the continental version.

Hi
small problem , I was about to phone 50cycles today to buy this agattu thing! firstly influenced by Flec amazing test report, and most of the other positives about the Agattu. however ten minits ago I went outside to look at my old bike (bit of an off roader 10 years old) and have problems, despite the discolated shoulders, and the odd stitches it cost, it still shines and becons,
Due to a rendevou with the surgeon when they finish their holiday break, I cannot ride at the moment, but is there any kit that will make my friend close to the Agattu..I particularly like the pedalac idea..think always having bought "Royce" quality hardware in the past I don't really want a second rate machine.
(by the way sad thing..on the continent "Rolls Royce" has been superceeded by "Alles Bialetti" as a sign of engineering.

You can certainly get kits to electrify your existing bike, but they tend to be hub motors - I don't know of any that drive through the gears like the Agattu, although there may be some. The only kit I have experience of is the German-made Heinzmann, and they aim for quality. Details on this site:
Heinzmann E-Bikes & Retrofit Kits - Emotive Control Systems - Estelle Electric Bikes - Pedelecs - Recumbents - Heinzmann Hub Motor

I'm sure you'll get other options suggested.

i would hang on to see what the new Powabyke is like..from another post it looks like styling will be up to date,,,performance should be at worst the sames as existing models and it will almost certainly be cheaper than the Aguttu.....can't wait !
