Hello lads, how I said in my other post I've been thinking in spending some. More money but I don't know if is really worth it or not, and are some things that I can't understand.

I've seen the bh bosh system bikes and with a 9ah battery they say you can range up to 90-100km, is that true? I see is too much for that battery but I don't know if is because of the bosh system..

I've read many good reviews about the bh( and a high power torque) many good about the a2b hybrid.

For less than that price I may could get a good ezee bike and for much less the woosh.

I've read there is not a big difference on the quality of woosh bikes but, apart that because woosh make their own bikes, where else is that big difference on price?

For all the people that tried lots of pedelecs which one under 25kg with high power, and throttle is the best you ever tried?( I know depends on what you want the bike for and likes, but would be good to have some kind of list about the best quality bikes on each range of price or function)

Thanks lads

I can flatten a Bosch 9ah battery in just 12 miles. Or eek out about 20 miles max.

Is that with lots of assistance and in a very hilly area?

It is yes, and high speed too.

That's sound very enjoyable!Which bike do you have?

the one in my signature and avatar. and yes it's a fantastic bike. a 30 ah battery would be nice.

You'd get a 17Ah battery Kalkhoff Impulse bike for that kind of money, giving you greater autonomy and a top spec bike. Look at the Pro Connect series. The combination of a 'sorted' motor, with a powerful battery, all in a quality bike and all within budget should not be overlooked. The shift sensor in the I2 motor works just great, from my experience.

Looks great!The Ktm macina is one of my options too. Did you try any other ebike similar to your bike?

Can you fit a bigger battery there?

As above a Kalkhoff impulse would be a very good option. Although I've never ridden one so can't comment on how they compare to the Bosch system. My bike is near perfect for me bar the battery capacity, I have 2 batteries now, but could do with more capacity really.

When I rode a Bosch bike I knew that was the system for me, and when my bike came up for sale at £1400 brand new the decision was made.

I've been looking at the kalkhoff and looks like a good quality bike, I prefer the way it looks the other kind of bikes but as you said it can be a good option thinking about spec and battery

1400 brand new for the Ktm I think was a great value, the best thing is that you like it and you can enjoy it

I'm sure you already know but just in case, none of the Bosch powered or Kalkhoff bikes have throttles - in common with all European made bikes.

The Bosch and Impulse (Kalkhoff) crank drives feel similar (there will be various opinions on which is best) but the major advantage of the Kalkhoff is the real (as opposed to claimed) range and the likely (in this case both claimed) longevity of the battery.The quality of standard bike components on the Bosch powered bikes varies (KTM look good) and Kalkhoff have always used top quality components.

What about the neo xtrem? That has same kind of battery 9ah they say same range and has throttle.

I could be wrong but I think the BH Neo bikes use the same motor branded 'Xion' in the Kalkhoff stable. This is a great motor. The battery range quoted will be with minimal assistance on the flat. In real life about half that would be more normal. 9ah = 15-30 miles if there are any hills and you use max assist some of the time. I believe the throttle will only be on bikes exported to USA. There is a button that will propel you along at 6km/h which is similar to the walk assist function provided on other European made bikes.

A bit of further research suggests the BH Neo bikes use a 'Dapu' motor, not the similarly named 'Neodrive' that Kalkhoff use and brand as 'Xion'. Dapu motors have also been used on Wisper bikes (possibly not the same motor). The Dapu motor on my Wisper is quite noisy in comparison to the Xion. This may not be the case with the Dapu motor on the BH Neo bikes.

Right first time. You were wrong - as you figured out The Neos have a Dapu or Bafang geared hub-motor with internal clutch. The Xion motor is direct drive, so no clutch, which is why you can't go fast downhill on the Xion. They're two totally different motors and control systems and behave/feel totally different.

How good are this motors? Are they better than other ones or just different?

You can find a summary of the main (premium) motor systems on this american website http://newwheel.net/electric-bike-basics/electric-bicycle-motor-systems. I only have experience of the Xion, Impulse, Bosch and Dapu (on the Wisper). I believe the Dapu motor on the BH to be different and I have only tried this on a very short test track so I'm not really able to comment on it. I'm not sure what d8veh means about the Xion being slow downhill. I've easily topped 40mph on it, but it's the power uphill that is most significant.

I don't think that there are any bad motors these days. The Dapu and Bafang CST motors used in the Neos are both very strong, powerful, quiet, and have the splines for cassette gears so that you can have nice gears.

The Xion motor is direct drive, so no clutch, which is why you can't go fast downhill on the Xion.

 

My Xion-motored PC goes downhill just as easily as my other two ebikes so I don't understand your statement. It's a nice motor, providing a smooth, quiet drive with enough torque to get up most hills at a fair lick.

 

The energy replenishment is nice on the spec sheet but in practice, pretty useless really. I keep it switched off now and the only point I can see in switching it on is for the engine braking effect, saving a little on brake pad wear. For all that brake parts cost, I'm happy to pay for replacement when they wear down so the energy recovery/brake assist is pretty superfluous on my bike.

I think you tried many ebikes, could you tell me if you feel a big differencein how powerful are or on the quality comparing the bafang from woosh to the bh,Bosch,etc?

Or the differenceon the price start in the quality of the battery cells?

The main difference is the quality of fork and brakes.

The Woosh Big Bear and the Woosh CDs are just as powerful and fast as any of the £2000 bikes you are likely to find. Woosh sell a lot of bikes to commuters so they put kevlar tyres on all their bikes except the Sport.

Is this the same for the Woosh sirocco 2?

Do you think that is worth spending another 1000 on the forks and brakes?

It depends on your point of view, you'll get different answers from different people. If you know about bikes, the difference in overall quality is pretty evident. Frame, gears, brakes, forks, tyres, cranks, bars etc - all components and it all adds up. The latest budget motors are by all accounts pretty good and the battery is more a question of range, longevity and appearance. If as a customer you are inclined to go for quality, you will notice the difference. If you are more a car is a car type of person then the budget bikes will seem just as good. Like beauty, quality is in the eye of the beholder.
