Now't wrong with a BPM front hub very strong climber an plenty of torque ideal combined with a 15ah 30Q battery though op will probably need a 17.5ah one for 60 miles.

If so, it sounds good to me!

the OP can also have these hubs fitted to the rear wheel, better traction.

Better for damp conditions. Could well be the go.

OK, change of plan

I have been speaking with the Mrs and decided to buy a off the shelf bike.
This is partly so the wife can use the eBike when we are out together and she will be able to keep up. I also use my bike it a trainer and so a rear motored solution would not be ideal.

So my next question is what would you recommend I try. I have a budget of £2,000 I have shortlisted the Volt Pulse X, Emotion Evo Jet Lite (I like the integrated battery and removable rear wheel), Oxygen S-Cross CB.

As Im sure you would have noticed I looking for a Hybrid style bike, ideally with mudguards, lights etc, but I'm also attracted by styling.

Must have a cross bar to hand on a bike rack (tower mounted).

TIA
Darren

I am not saying that you are wrong but where can you find a ready made bike with a BPM or a BBS01/BBS02 (or with equivalent pulling power) for the price of a kit?

A kit's not much good without a bike to put it on. You therefore have to add the cost of a donor bike.

I've never found front hubs particularly great for that. Depending on rider weight a rear hub might cut it?
I'd worry a cheap front hub might disappoint and not deliver.

If you go for a front hub, you can get traction problems on very steep hills. You can get rear hubs that give all the climbing torque you want. For a bicycle, there's no limit.

Hi guys, I've stumbled across a Kalkhoff Agattu Premium Impuse 11, what are your opinions on these?

I found front hubs struggle on not so steep hills too, particularly if road surface is loose or wet. Double trouble when the bike is fitted with a rear carrier rack and loaded with fair to moderate weight and/or child . I dislike the way it makes the bike handle, with vague steering and drifty front wheel under power.
Rear hubs are an improvement, but I'm still not a fan of the weight distribution compared to a mid drive.
Sure, no limits.... a Mxus 3000W rear hub on the right bike is a whole lot of fun, BUT, limited to 250W as we are to qualify as EAPC in the UK, improved torque from a mid drive goes that bit further and used efficiently with the bike's gears maximizes the power we're legally allowed to use.
If it wasn't so hilly where I live, I may accept a decent rear hub, but there's still the weight distribution thing and I have a strong preference to the weight being centralised and low down rather than swinging around at the far back of the bike.
What can I say, I'm clearly a biased mid drive fan!

If you want legal, try a Xiongda hub-motor. The 48v one is like a winch in low gear. It'll change your mind about which type of motor is best for the road. Even a 48v 201 rpm Q128H from BMSB will have enough climbing power for those hills. Both of them are relative light, so I can't believe that you'd notice them at the back of your bike.

There's a very long thread running about Kalkhoff reliability. I suggest that you read it.

Thank you. I'll have to check them out. I'll look into a build this summer
Still slight reservations about ease of removing the wheel when out and about should I catch a flat tyre, plus tools required and the drop out suitability/ strength on certain bikes.
Not so important with disc brakes, but spoke/rim damage is also of heightened concern. The roads around here are far from smooth! I guess a higher quality rim and larger gauge spokes help.
For road riding/commuting I see they may be a good option.

Ok so Motor reliability is questionable on the Kalkhoff range, is there a mid drive that is within my budget and meets my requirements?

The Greenway one thath a couple of forum members managed to snag from Ebay are exceptional value. maybe send the seller a message asking him when he'll have some more. Also, they have this one, which is a tiny bit cheaper:

Do you know that motor is the same used on the Woosh Krieger and Santana CD?
