The all aluminium KV4 is based on decades of development of the Alleweder. The famous Alleweder velomobile goes back to the late 80’s. The KV4 is a complete redesign following the proven technology of the Alleweder. So it is a well developed product that has proven very suitable for everyday use. A prototype had already made over 10,000 km without problems before the first production run was started.
This kit is 2265 Euros but they don’t like to ship to US or Canada. VelomobileUSA sells the Flevobike Alleweder (FAW) for $3395 in kit form.
