heinzmann 450 euros = good price?

[qeeeme]

I found an offer:
pedelec bike (ktm(?)) 28" shimano nexave(?) 7 speeds. was bought in mai 2003 for 1650 euros new. now offered for 450 euros
battery 32 v nimh

motor:
heinzmann "egstorn II(?)"
written: n=144/min
In 9A Imax 20 Mmax 33Nm

the seller says that it goes to 18,5 km/h maxi. so it is corresponding to the indication n=144/min

- if i compare with the prices today for motors:

- heinzmann with battery and controller are more than 1000 euros
-cheapest in germany are chinese kits starting 200 euros (poor quality, no battery)

well for 450 euros i get a heinzmann motor

- for that price what other motor+controller+battery can i get? no one in this quality?

- the point is: this bike is maybe not the right one for me, i can bike well, but i like to put the heinzmann motor in another bike

-if the motor goes alone to 18km/h, then i can cycle with my muscles and get easily 25 km/h?

- if i dont buy this pedelec for 450 euros, what can i get for 450 euros? are they motors+controller+battery for that price?

-can i boost the motor with a 36v battery? (i have a 36v led battery)

thank you

I had a Heinzmann kit which I bought new. 500W, 36V with NiMH battery.The Heinzmann motor is very heavy, has brushes which need replacing (albeit after a long time) and mine was noisy too because it had metal gears. Personally, I would never use Heinzmann again. Although the motor is well engineered, I found it to be almost too well engineered... big, heavy aluminium casting (which oxidised rapidly to a horrible dull grey colour). The controller is large and heavy. The rack is heavy. The NiMH battery is heavy and needs to be discharged fully between charges (unlike Lead-acid or Li-Ion). This means you have to set out on a journey with only 25% full battery (for example) and you have to use the battery until it's completely discharged before you charge it up again. A major pain

Pedalling my Heinzmann bike was hard work because the Heinzmann kit weighed 10kgs........

Personally, I would go for a brushless, non-Heinzmann motor. I think you are wrong when you say that Chinese motors are poor quality. Technologically speaking, they are superior to Heinzmann in many ways. They are brushless, Hall effect, light, small, quiet and many give years of service. I would also go for a Li-Ion battery. Yes, this is not fully tested technology but they are light and can be charged after every use. OK, they may not last as long but I think it's better to pay for another battery than spend years of pedalling with a Ni-MH or lead acid battery........

This one sounds like the low speed version qeeeme.

Heinzmann make their 200 watt rated motor internally geared in different ways.

For a 26" wheel, the standard version gives 25 kph, the low speed version for better torque, hill climbing and load hauling geared for 18.5 kph, and the high speed version for sporting riding geared for 30.5 kph but with low torque.

The motor you've seen advertised is therefore unsuitable for your normal riding, hence the low price, not many wanting that version.

Just to clarify the current offering:

The standard Heinzmann kit has a 43Nm motor. This is rated at 22km/h and 12% hills in 26" rims and 24km/h and 11% hills in 28" rims. This has nylon gears to keep the noise down and is available as e-bike or pedelec. This is found in the Estelle range of bikes (Sport Speed excepted which has a 500W 38km/h motor and therefore not UK road legal)

There is a hill climber available rated at 55Nm which will achieve 24km/h (15mph) and 15% hills in 26" rims. The same motor in 28" rims is a bit fast for UK regs so a 50Nm, moderate hill climb version is also on offer for those who need it (14% hills on 28" rims and up to 22km/h).

Both these hill cllimbers have steel gears to cope with the extra torque, but as can be seen higher torque does not automatically mean losing out on speed.

As previously announced in another post Heinzmann are introducing a Li-Ion battery later this Spring in 5.2Ah and 9.6Ah, 36V version. These should allay any weight and charging concerns. Pricing to be announced. The 5.2Ah version weighs in a 2.3kg.

Also whether €450 is worth it may depend on how old the unit is. The first two digits after the F in the serial number denote the year of manufacture, the next two denoting the month.
